    摘要: A laser light source, comprising a semiconductor layer sequence on a substrate and having an active region and a radiation coupling out area having first and second partial regions and a filter structure. The active region generates coherent first electromagnetic radiation and incoherent second electromagnetic radiation, the coherent first electromagnetic radiation is emitted by the first partial region along an emission direction, the incoherent second electromagnetic radiation is emitted by the first partial region and by the second partial region. The filter structure at least partly attenuates the incoherent second electromagnetic radiation emitted by the active region along the emission direction. The filter structure has at least one filter element arranged on an area of the semiconductor layer sequence which has an extension direction parallel to the emission direction and which is remote from the substrate.

    摘要: Embodiments of the invention describe various configurations for a multi-wavelength laser cavity. A laser cavity may include a shared reflector and a plurality of reflectors. Each of the plurality of reflectors and the shared reflector together form one of the plurality of output wavelength channels.A shared filter is utilized to filter the optical signal of the laser cavity to comprise a subset of a plurality of cavity modes. A (de)multiplexer, comprising a plurality of filtering elements), receives the optical signal and further selects and separates the final lasing wavelengths from the selected subset of cavity modes, and each filtering element outputs an optical signal having a wavelength for one of the output wavelength channels.

    摘要: A single-pump multi-wavelength lasing semiconductor Raman pump laser comprises a thermoelectric cooler arranged in a shell; a heat transition bearing platform arranged in the thermoelectric cooler; a semiconductor Raman pump laser tube core arranged on the heat transition bearing platform; and a coupling lens group, a thermistor and a backlight detector that are arranged on the heat transition bearing platform respectively. The pump laser tube core, the backlight detector, the thermistor and the thermoelectric cooler are electrically connected to pins outside a laser tube shell. A pump combination apparatus comprises a first signal transmission fiber, a pump signal combiner and a second signal transmission fiber that are sequentially connected to each other. An input terminal of the pump signal combiner is connected to an output terminal of an isolated polarization beam combiner and depolarizer. Two polarization maintaining fiber input terminals of the isolated polarization beam combiner and depolarizer are correspondingly connected to one single pump multi-wavelength lasing semiconductor Raman pump laser respectively.
