Below, we present a formulation which allows the calculation of the quantum efficiency, finesse, and free spectral range of an arbitrary RCE detector structure.
Special consideration is given to solutions which yield near unity quantum efficiencies.
We also consider the dependence of RCE detector properties on the placement of the active layer within the cavity and the angle of incidence of the detected radiation. Finally, a formulation for spontaneous emission within an optical cavity suitable for LEDs is presented.
