Product Overview:

1577.9nm Sumitomo SLT 5411-CB-F000 20mW DFB Laser

SLT5411 series DFB laser diodes are 1.5μm InGaAsP/InP MQW DFB laser diode modules designed for a CW optical source of WDM (Wavelength Division Multiplexing) application used with an external modulator.

A laser diode chip is mounted on a 14-pin butterfly package integrated with an optical isolator, an InGaAs monitor PD, a thermo-electric cooler, and a single mode polarization maintaining (PM) fiber pigtail.

Important Notes on Operating Laser Diodes:

Electrical Operation: Operating a laser diode above the maximum ratings shown on the data sheet even for very short periods of time can damage the laser diode or reduce its lifetime. They should be electrically biased with a ""laser diode driver"" class current supply with low electrical noise and protection against voltage and current surges. Laser diodes are very sensitive to electrostatic discharge (ESD). Proper ESD precautions must be taken.

Mounting and Temperature Control: In order to maintain the lifetime of a laser diode, proper heat management is essential. Due to the design of the laser diode, heat is typically dissipated only through the base plate of the diode‘s package. A proper heat conducting interconnection between the diodes base plate and the heat sink must be maintained. Some devices require the use of a thermo-electric temperature controller (TEC controller) to remove the heat from the laser and stabilize the temperature.
