Abstract

A heterostructure for resonant-cavity p-i-n photodiode was grown by molecular beam epitaxy and consists of light-absorbing GaAs i-layer between p- and n-emitter layers of AlGaAs. The heterostructure employs Bragg reflector with more than 95 % reflection coefficient at 840-860 nm wavelength. Photolithographic masks for chip fabrication were designed using optoelectronic and thermal phenomena simulation. Fabricated chips exhibit a bandwidth of 10 GHz and low dark current.
