摘要：
Here, we present the output characteristics of a semiconductor laser diode with two circular ring resonators. The material of the laser diode is a metal organic chemical vapor deposition (MOCVD)-grown InGaAIP multiple-quantum-well (MQW) structure. The current injection of the laser diode is confined by the ridge waveguide of two circular ring resonators connected by two directional couplers. The confined light output through the nonwaveguide region of the substrate was observed. Measurements of light-current (L-I) and spectral characteristics at each output terminal were presented. These measurements showed asymmetric output characteristics of emission from two directional coupling terminals. In addition, output characteristics of a laser diode device with larger diameter ring resonators showed shifting of the lasing emission wavelength from a different side of the output coupling terminal.
