Depolarisiertes Halbleiterlasermodul, Verfahren zu seiner Herstellung und Ramanverstärker

Depolarised semiconductor laser module, manufacturing method thereof and Raman amplifier

Abstract

A semiconductor laser module (1) comprising a semiconductor laser device (6), a pigtail fiber (5), and optical lens (2c) disposed to optically couple the semiconductor laser device to said pigtail fiber, a method of manufacturing the semiconductor laser module, and a Raman amplifier. The pigtail fiber (5) is a polarization maintaining optical fiber with a polarization maintaining axis shifted by a predetermined angle with respect to a polarization direction of a laser beam emitted from the semiconductor laser device.
