Characteristics of a uni-traveling-carrier photodiode(UTC-PD) are investigated.A hydro-dynamic model is introduced which takes into account the electrons’ velocity overshoot in the depletion region,which is a more accurate high speed device than using the normal drift-diffuse model.Based on previous results,two modified UTC-PDs are presented,and an optimized device is obtained,the bandwidth of which is more than twice that of the original.
Characteristics of a uni-traveling-carrier photodiode (UTC-PD) are investigated. A hydro-dynamic model is introduced which takes into account the electrons’ velocity overshoot in the depletion region, which is a more accurate high speed device than using the normal drift-diffuse model.Based on previous results, two modified UTC-PDs are presented, and an optimized device is obtained, the bandwidth of which is more than twice that of the original.
