Interferometric semiconductor laser with low loss outcoupler and assembly comprising such a laser

摘要

The appts. includes e.g. a so called Y-laser (YL) with a number of independently controlled segments (1-4), one of which is a coupling segment (2). An output coupling stage (Z) is provided at the end of the coupling segment which is reflection free. Connected to the coupling segment are two arm segments (3,4) and a root segment (1). The output coupling element may be coupled to a monolithic structure at its output end.
