Advanced Fiber Optic Sensors

Evanescently coupled photodiodes have been designed for hybridisation on an Si platform. Diluted multimode waveguides have been optimised with a genetic algorithm. High efficiency photodiodes at both 1.3 and 1.5 µm, with very low polarisation dependence, have been fabricated with low bias, 2.5 Gbit/s capability and high reliability.
