Characteristic analysis of resonant-cavity-enhanced (RCE) photodetectors

Analyses of light field distribution within a lossy resonant-cavity-enhanced (RCE) p-i-n photodetector is performed. A new expression for the field distribution inside the cavity is derived. This expression is used to derive an expression for the quantum efficiency taking into account the standing wave effect. The field distribution expression is also used in the continuity equations to derive and evaluate the frequency response of the RCE photodetector.
