Comment this PageDFB Diode Lasers, Single Mode
Single ModeDescription:
Distributed Feedback (DFB) Diode Lasers are single mode diode lasers. The single mode emission is enforced via a Bragg grating with the laser chip. Frequency tuning is available via laser temperature and / or laser current variation.
Distributed Feedback (DFB):
Distributed Feedback (DFB) Diode Lasers are fixed wavelength single mode diode lasers. Typical geometrical sizes of the laser chip are 1000µm x 500µm x 200µm (length x width x height). The laser chip is grown by MOVPE of compound semiconductor material. The optical gain is provided by double heterostructure which include several Quantum Wells for electronic confinement. Typcal emitter width range between 3µm and 7µm. The single mode emission is enforced by a Bragg grating with the laser chip. The surfaces of the laser chip act as cavity mirrors due to the difference of the refractive index of the laser material and the surrounding air. The rear facet of the laser chip is provided with a high reflection coating. The front facet of the laser chip is provided with a high quality antireflection coating for avoiding the Fabry Perot modes of the laser chip. Distributed Feedback (DFB) Diode Lasers are available at almost any wavelength between 760nm and 2800nm.
Packaging Options:
DFB Lasers are available in 9mm TO-cans, TO3 cans with an integrated thermoelectric cooler or butterfly packages with thermoelectric cooler and single mode fiber coupling. Please note that the output power is reduced to typically 20% of the nominal power for the fiber coupled butterfly versions.
Customized Wavelength Selection:
Available wavelength range from 750nm to 1630nm. Due to a special manufacturing method, customized wavelength can be provided with a selection of below 2nm even for single units. Please check our most commonly requested wavelength.
