    Abstract

    The COMBlaser project aims studying the basic physics and designing single section Fabry Perot Lasers (FP-Ls) to be used as comb sources at optical communication wavelengths or in the MidIR. For optical communication wavelengths we will consider Quantum Well, Quantum Dash and Quantum Dot active materials grown on InP or GaAs; for the MidIR range we will consider Quantum Cascade Lasers. Several experimental works have shown that some FP-Ls in thesematerial systems can produce an output spectrum of phase locked longitudinal modes but a quantitative and comprehensive physical explanation of the phase locking mechanism is still missing. The project aims developing physical models and simulation tools for these devices and use them to explain and compare the self modelocking in these nanostructured lasers. Thanks to the developed tools, we will also provide guidelines for the design of FP comb lasers at 1.55µm and we will move first steps toward the design of this sources in a Silicon photonic platform. Simple comb lasers at telecom wavelengths are indeed of high interest for the industry as they could potentially replace the complicate DFBs array used up to now as WDM source in computer links in data centers.

    Abstract

    The 'Development of low-cost technologies for the fabrication of high-performance telecommunication lasers' project has two main objectives:<br/>(1) Development of high-performance surface-grating-based DFB/DBR telecommunication lasers<br/>(2) Development of ultra-high speed directly modulated lasers (> 40 GBit/s) with a simplified multi-section design, which exploit high-order photonic resonances for extending the modulation bandwidth.<br/>The project approach is to develop a common technological fabrication platform for both types of lasers based on surface gratings and other surface micro- and nano-structures. One important advantage in using surface structuring for increasing the performances and functionality of edge-emitting lasers is the elimination of the regrowth stage, which adds to the fabrication cost, affects the laser performances (notably the reliability and the characteristics shift in time) and reduces yield. The surface micro- and nano-structures will be imprinted by the low-cost and high-yield nanoimprint lithography, which will contribute to reducing the fabrication cost.<br/>The developed surface-oriented technology will be largely independent on the underlying semiconductor structure and will be applied for the fabrication of InP- and GaAs-based edge-emitting lasers (EELs) working in the 1300 and 1550 nm ranges. Although advanced materials (like dilute nitrides and antimony-containing dilute-nitrides) as well as low-dimensional structures (quantum dots and quantum dashes) will be investigated for developing the active regions of the lasers, the surface-oriented technology will be directly applicable to epitaxial layer structures already developed and tested in regular Fabry-Perot telecommunication EELs. Thus the developed surface-oriented approach will have the unique advantage of enabling the fabrication of higher-performance lasers from already tested and qualified 'legacy' epiwafers.

    Abstract

    FAST-DOT aims to implement a new range of ultrafast quantum-dot lasers for critical bio-medical applications. This project will develop portable, low-cost, reliable, highly efficient ultrashort pulse and ultra-broadband tuneable laser sources. The key technical innovation – quantum dots (QDs) - are based on novel semiconductor nanostructure clusters which demonstrate remarkable new photonic properties. QD structures will afford major advances in ultrafast science and technology by exploiting the unique combination of QD properties (high optical quality, efficient light generation, ultrafast carrier dynamics and broadband gain bandwidth) at wavelength range which not easily accessible with current technologies. The FAST-DOT consortium brings together a unique and compelling group of world-leaders in the physics of QDs and QD photonic devices, system integrators and biophotonic. This research will realise a full understanding of the underlying ultrafast properties and physics of QD structures and exploit these effects in the construction of novel highly compact, reliable and environmentally-stable sources of ultra-short pulses. The new QD sources will be investigated and validated in a range of bio-photonic applications including OCT; Non-linear Microscopy; Nanosurgery and minimally invasive diagnostics. The availability of compact and inexpensive ultrashort pulse lasers will have widespread impact in uptake by making many applications more affordable and opening up new application areas. The project unites 18 complementary European research groups and companies with international reputations in the development of semiconductor materials and their use in efficient ultra-fast lasers, related applications and marketing. All of the groups have record of collaboration and a strong record in producing high quality results and joint publications. This programme will contribute to further extending Europe's world-leading position of in photonics and ultrafast technology.

    Abstract

    The key objective of this project is to develop optical broad bandwidth sources using the unique properties of multilayer quantum dots structures and nonlinear photonic crystal fibres for bio-photonics applications. The proposal presents a unique synergy between nanotechnology, information science and technology and life sciences. The source development is targeted at biomedical applications such as: * Optical coherence tomography (OCT): an emerging, non-invasive, imaging technology for diagnosis (age macular degeneration; skin cancer) * Medical instrumentation based on spectroscopy For OCT in particular, the lack of optical bandwidth in available commercial technology is the main bottle-neck in achieving ultra-high resolution imaging systems. Addressing this issue enables successful penetration of this important diagnostic tool into hospital clinics. To overcome this bottle-neck, we propose to develop a breakthrough technology based on innovative concepts. The core technology development in the project is based on the most recent scientific advances in quantum dot materials. The use of these nanoscale strained islands provides the unequalled advantages of access to wavelengths and to broadband gain spectra not reachable by quantum well technology, thus overcoming the limiting bottle-neck of current laser sources. Two pathways will be investigated for achieving large optical bandwidth with sufficient power levels together with high beam quality and low noise: * Quantum dot (QD) superluminescent diodes and wavelength multiplexed QD superluminescent diodes * High peak power, pulsed QDs lasers, based on mode locking, for the pumping of nonlinear photonic crystal fibres to achieve significant spectral broadening The resulting developments from this project will enable unprecedented early diagnosis of diseases that are worldwide leading causes for blindness, cancer diagnosis of neoplastic changes and real time therapy monitoring in dermatology.

    Abstract

    The leading thread of this NoE is photonic integration. The integration of complex or high performance photonic functions will become the key enabler for a cost-effective and ubiquitous deployment of photonics in a wide range of applications, including ICT, sensors and biomedical applications. The technologies needed for photonic integrated components and circuits are characterised by high investment and exploitation cost. This calls for more integration of research at an international level. Therefore the mission of ePIXnet is three-fold. The first objective is to stimulate the restructuring of the photonic integration research community from a model of independent or collaborative research towards a model of integrated research. The second is to stimulate training activities as well as integration of educational programs. The third objective is to stimulate new opportunities for photonic integration in a wide range of application domains.The NoE will contribute to the strategic objective: Optical, opto-electronic, photonic functional components and will focus on five major themes: photonic integration technology, nanophotonics, advanced semiconductor materials, ultrafast light sources and ultrafast signal processing. The network brings together most of Europe's strongest academic and industrial actors and will contribute to the quality of education and research by stimulating long lasting partnerships and by providing access to unique facilities and knowledge in the field. To this end the steering committee has selected 5 specific Facility Access Activities and 9 specific Joint Research Activities on the basis of their potential for research integration. The network will also develop an active program of exchange of researchers, of institutional collaboration agreements, web-based information exchange and dissemination etc. Furthermore the network will have an open policy to include affiliate partners in particular industrial affiliate partners.
