Abstract
We fabricate a tensile-strained InGaAsP-InP quantum-well (QW) laser with coupled two disks, emitting at 1.5μm. For a microdisk with radius of 10μm and a 2-μm-wide output waveguide, a continuous-wave (CW) threshold current is 24mA at room temperature and the mode intervals of 2 and 5.3nm are observed, corresponding to splitting of symmetric and asymmetric modes, and longitude mode space. The peak intensity of main mode is 25dB higher than the background with the wavelength of 1522nm at 115mA.
