DFB & DBR Lasers
Distributed feedback (DFB) and distributed Bragg reflector (DBR) laser diodes include a monolithically integrated grating (Bragg reflector) as a spectrally selective intracavity element. In contrast to Fabry-Perot lasers, they can generate in a single longitudinal mode, typically with the optical linewidth between few hundreds’ kHz and few MHz.
Innolume offers a broad portfolio of high power, spatial single-mode laser diodes of any wavelength in the 780nm to 1340nm range. Devices are available either packaged in a 9-mm TO-can with a single-mode or polarization maintaining (PM) fiber coupled standard 14-pin butterfly package.
Gain-chip is the irreplaceable component as a gain medium for the building of the tunable diode laser or high stable external cavity diode laser. Gain-chip is similar to laser diode chip except the fact that it has deep antireflecting coating on one or both facets which significantly increases threshold of self lasing or eliminate it.
The Gain-Module is a similar device to the Gain-Chip, but has one side coupled into single mode fiber. It is greatly applicable for building tunable lasers with a fiber output. Factory made fiber coupling ensures optimized coupling efficiency, long-term stability and excellent reliability.
Laser Diode Drivers
Innolume offers several compact solutions including 14-pin butterfly mount, current driver and TEC controller in one box. Drivers provide fast and convenient powering of any of Innolume single mode fiber coupled device such as High Power FP/FBG laser, SLD/SOA, or DFB/DBR. Being purchased in one batch, the laser will be comprehensively tested together with the driver.
