Paper Abstract

A novel guard ring p-i-n photodiode is designed and fabricated to solve the slow-tail problem associated with typical p-i-n photodiodes. The device incorporates an additional diffused p+ region around the active layer to circumvent the problem of slower responses due to diffusion currents. The effectiveness of the guard ring in providing low Bit-Error-Rate is quantified. The Extinction Ratio of the device with a 20nsec pulse is in excess of 31 dB.
