Abstract

InPGaInAsP square-resonator microlasers with an output waveguide connected to the midpoint of one side of the square are fabricated by standard photolithography and inductively-coupled-plasma etching technique. For a 20-μm-side square microlaser with a 2-μm-wide output waveguide, cw threshold current is 11mA at room temperature, and the highest mode Q factor is 1.0×104 measured from the mode linewidth at the injection current of 10mA. Multimode oscillation is observed with the lasing mode wavelength 1546nm and the side-mode suppression ratio of 20dB at the injection current of 15mA.
