Abstract :
The fabrication of quantum-dot-based optoelectronic integrated circuits incorporating twin ring diode lasers, waveguides, directional couplers, a Y-junction mixer, and photodetectors, is reported. Microwave frequency beating between longitudinal modes from individual ring diode lasers as well as beat notes between integrated twin ring diode lasers are demonstrated.
