Abstract

Resonant cavity enhancement (RCE) typed optical detector and modulator which operating at wavelength band of 1.06 ?m is reported. The peak quantum efficiency of detector is reasonably high as 50% without bias, and the photocurrent contrast ratio of modulator is 3.6 times at -3.5 V as compared to 0 V. The incident angle dependence of RCE device's photoelectric response is investigated carefully.
