Abstract :
Low-power phototransceivers and phototransceiver arrays, with vertically integrated high-gain heterojunction phototransistors (HPTs) and resonant-cavity light-emitting diodes (RCLEDs), are demonstrated. A tunnel junction was used as a low resistance interconnect between the two devices. The input and output wavelengths are 0.63-0.85 and 0.98 μm, respectively. The phototransceiver exhibits an optical gain of 13 dB and power dissipation of 400 μW for an input power of 5 μW. The phototransceiver arrays demonstrate good uniformity, low optical crosstalk, and imaging capabilities.
