Abstract
We designed and fabricated lateral-current-injection (LCI) Fabry-Perot (FP) lasers for the 1.3-μm wavelength region. The devices were fabricated using selective doping by means of thermal diffusion and ion implantation to make pn junctions. To increase the optical confinement factor in the active region, we used an InGaAlAs-based 20-quantum-well structure. The device exhibited a threshold current of 16 mA and differential efficiency of 47% for a 400-μm long and 0.5-μm wide cavity. We also measured the relative intensity noise (RIN) spectrum to obtain parameters for the direct modulation. The LCI FP laser provided both high output power and high relaxation oscillation frequency.
