Redfern Integrated Optics Inc. has announced that its Planex and
Orion laser module platforms are available with higher minimum output power, up
to 20 mW, without the need for an external optical amplifier. The higher output
power adds to the lasers’ specifications in linewidth, phase noise, relative
intensity noise and Telcordia reliability. The lasers operate in the C-band from
1530 to 1565 nm and are narrowly tunable. The higher output power, low noise and
ultranarrow linewidth of <3 kHz make these semiconductor optical solutions suitable
for use in applications where absolute accuracy, lifetime reliability over demanding
field conditions, and high resolution are vital, such as remote sensing, distributed
temperature, strain, acoustic fiber optic monitoring, high-resolution spectroscopy
and lidar.
