Semiconductor injection locked lasers and method

摘要

In one aspect, the invention relates to a semiconductor laser. The laser includes a substrate and an elongate unitary laser structure disposed on the substrate. In turn, the elongate unitary laser structure includes a first laser section, a second laser section, and a plurality of shared layers. The first and second laser sections are capable of lasing independently of each other. The shared layers form both the first laser section and the second laser section. The first laser section is adapted for injection locking the second laser section.
