Abstract

Summary form only given. A laser diode with a spot-size converter provides highly efficient coupling to the optical fiber without using lenses and provides a wide alignment tolerance in an optical module assembly. In this paper, the active region is optimized using a strained multiple quantum well (MQW) that has been buried with pn-heterostructure (pn-BH) to improve the maximum output power and laser operation at high temperature. Furthermore, we studied and optimized the 2D far-field pattern (FFP) of a laser beam.
