Abstract :
A new ECTT-DHPT with InGaAsP(lambda=1.55 mum) as base and InGaAsP(lambda=1.3 mum) as collector as well as waveguide was designed and fabricated, the DC characteristics reveal that the ECTT-DHPT can perform good optoelectronic mix operation and linear amplification operation by optically biased at two appropriate value respectively. Responsivity of more than 52 A/W and dark current of 70 nA (when Vce=1V) were obtained.
