Semiconductor laser for optically pumping semiconductor appliance, with semiconductor body containing periodical system of recesses, or periodical system of semiconductor regions so that laser generated radiation

摘要

Semiconductor laser has body (1) with periodical system of recesses (2), or periodical system of semiconductor regions. Radiation, generated by semiconductor laser cannot propagate within periodical system and laser resonator (3) is influenced in lateral direction by periodical system.Optically pumped semiconductor appliance comprises vertical emitter (13), containing quantum dot structure (7) and is pumped by one or more lasers. Preferably resonator has angled or curved axis. Independent claims are included for optically pumped semiconductor appliance.
