中文摘要	we have studied the optical matching layers (omls) and external quantum efficiency in the evanescent coupling photodiodes (ecpds) integrating a diluted waveguide as a fibre-to-waveguide coupler, by using the semi-vectorial beam propagation method (bpm). the physical basis of oml has been identified, thereby a general designing rule of oml is developed in such a kind of photodiode. in addition, the external quantum efficiency and the polarization sensitivity versus the absorption and coupling length are analysed. with an optical matching layer, the absorption medium with a length of 30 mu m could absorb 90% of the incident light at 1.55 mu m wavelength, thus the total absorption increases more than 7 times over that of the photodiode without any optical matching layer.
