Abstract
We demonstrate two high-performance photonic-transmitters based on uni-traveling-carrier-photodiode (UTC-PD) and separated-transport-recombination- photodiode (STR-PD). Thanks to recombination center, STR-PD exhibits comparable maximum-peak-power and electrical pulse-width with much smaller photocurrents and less serious device-heating to those of UTC-PD. ©2009 IEEE.
