Abstract

A high saturation current InGaAs photodiode with a partially depleted absorber (PDA) was demonstrated. To study the compression current as a function of applied bias, a 34-νm diameter device was illuminated with a 10 GHz small modulated optical signal while the average optical power from a CW laser was varied. Small-signal compression currents greater than 55, 31, and 20 mA were achieved at 10, 17 and 45 GHz, respectively. This resulted in a current-bandwidth product as high as 900 mA-GHz.
