Isolated DFB Laser Module with PMF
Applications
Description
The D2525P family of DFB laser modules is
designed to be used with a lithium niobate external
modulator (see Table 4). The laser module features a
polarization-maintaining fiber (PMF) pigtail, enabling
it to be directly connected to a modulator without the
need of a polarization controller. The PMF maintains
the polarization of the output light to a consistent ori-
entation. This allows the D2525P to be used as a CW
light source for systems requiring extremely low chirp
such as undersea or 10 Gbits/s systems. The module
contains a multiquantum-well (MQW), distributed-
feedback (DFB) laser. This device nominally has an
output power of 10 mW. The wavelength of the laser
can be temperature-tuned for more precise wave-
length selection by adjusting the temperature of the
internal thermoelectric cooler.
