Abstract
The absorption coefficient of an InGaAs PIN photodiode integrated with an InGaAsP-InP waveguide is analysed by means of the mode-matching technique. The results compare excellently to published data for X = 1-3 jan. It is shown that by an optimised device structure the absorption coefficient can be increased to about 0.15dBμm, enabling reduced detector length and smaller capacitance.
