The programme aims to develop and investigate a new class of miniatujre coherent optical sources for the near- to mid-IR by using parametric processes in semiconductor waveguides. These processes, which have hitherto been confined mainly to bulk nonlinear materials, will be extended to semiconductors by using novel QPM techniques based on quantum well disordering in semiconductor waveguides. This will enable the exploitation of the high nonlinearity of semiconductors, while overcoming their inherent phas-matching limitations due to a cubic structure. This will allow the use of semiconductors in frequency conversion applications, particularly the generation of tunable near- to min-IR radiation using parametric processes.The main objectives of the programme at St Andrws will be the successful deomonstration of such processes in semiconductor waveguides fabricated at Glasgow University. This will involve the generation and measurement of culminating in the development of a semiconductor waveguide OPO.The project is a major step in the realisation of novel integrated photonic sources based on the mature semiconductor technology in combination with the timely advances in optical frequency conversion and nonlinear optics by bringing together a unique set of capabilities at Glasgow and St Andrews.
