【 摘 要 】

The photonic quantum ring (PQR) laser is a threedimensional whispering gallery (WG) mode laser and hasanomalous quantum wire properties, such as microampereto nanoampere range threshold currents anddependent - T thermal red shifts. We observed uniformbottom emissions from a 1-kb smart pixel chip of a 32×32InGaAs PQR laser array flip-chip bonded to a 0.35 µmCMOS-based PQR laser driver. The PQR-CMOS smartpixel array, now operating at 30 MHz, will be improved tothe GHz frequency range through device and circuitoptimization.
