Product Overview:

1550nm DFB Laser Diode Overview

These single frequency 1550nm DFB laser diodes offer up to 40mW of laser output power with a very narrow line width emission profile of < 50 kHz. These lasers are also wavelength tunable.

DFB Laser Applications

DFB lasers are used in applications such as sensing, telecommunications, spectroscopy and atomic physics. They employ Bragg diffraction gratings in the active gain region of the semiconductor to form a waveguide. These 1550nm devices are an industry standard butterfly package with a "Type 1" pin configuration. The butterfly package is electrically floating, allowing for mounting flexibility and bias current source selection flexibility. The butterfly package includes an internal 10K thermistor, a TE cooler and a monitor photodiode.
