Ultrabroad bandwidth light sources based on nano-structuring devices

Projektbeschreibung


Materials, Equipment and Processes for Production of Nano-Photonic and Nano-Electronic Devices

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.
