Abstract
Abstract—A wide-aperture ridge waveguide structure was applied to 1.3- m InGaAsP–InGaAsP multiple-quantum-well laser diodes (LDs) to increase their maximum kink-free output power under single-lateral-mode operations. As a result, a kink-free output power up to 140 mW and an external efficiency of 0.3 W/A were achieved from a single facet of the LD with a 7- m-wide ridge top and a 1.5-mm-long uncoated cavity.
