1625nm DFB Butterfly Fibre Coupled Laser Diodes are manufactured by BoxOptronics. They are distributed feedback cavity design semiconductor lasers in mounted in an industry standard 14-pin butterfly package. They have an integrated TE cooler and an integrated back facet monitor photodiode. They have a spectral width of approximately 2 MHz. This narrow linewidth makes them an excellent choice for spectroscopy and gas sensing applications as well as telecom applications. They are specified with output power up to 10mW. The butterfly package has a single mode fiber pigtail which has an FC/APC connector termination. These 1625nm DFB Butterfly Fibre Coupled Laser Diodes are well known for their high reliability and long term stability.
