Product Overview:

1550nm DFB Laser Diode Overview

These single frequency 1550nm DFB laser diodes offer up to 40mW of laser output power in CW mode. Their key features include their single longitudinal mode (single frequency) emission profile, high stability, as well as a high output power. They are also tunable. 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 offered in an industry standard butterfly package with a "Type 1" pin configuration. The butterfly package is electrically floating, allowing for flexibility in mounting and selection of the bias current source. The butterfly package includes a 10K thermistor, a TE cooler and a monitor photodiode.
