Abstract :
A novel integrated dielectric filter-photodiode is reported, together with the first results of reliability testing of the device. The filter-photodiode has been designed as a low-cost demultiplexing element for use in passive optical local networks. It combines an evaporated multilayer filter structure and a conventional planar InGaAs p-i-n photodiode in a single device. Results of initial reliability stress-tests indicate that good reliability can be expected from the device in service, even when operated in a non-hermetic package
