Paper Abstract

A low dark current, high speed InGaAs PIN photodiode suitable for optoelectroinc integration has been fabricated by LPE method on sem-insulating InP substrate. The photodiode has a low dark current density of 2.5x10-6A/cm2 at -10V. At the operating voltage of -5V, external quantum efficiency of >90% at 1.3um and >83% at 1.55um, a rise time of <35ps and a FWHM of <45 ps have been measured. The approach and limitations to the design of a higher speed PIN photodiode will be discussed. The importance of packaging is emphasized, and pulse distortion due to dispersion in miscrostrip line will be discussed.
