Fabry-Perot Laser Diode
High-power 1550 nm laser diode
(Preliminary)
DESCRIPTION
Quantum Photonics’ Fabry-Perot (FP) laser diode is based on a high-power InP ridge waveguide laser structure. Advanced epitaxial
wafer growth techniques and die bonding processes enable high-power laser diode operation in the eye-safe 1550 nm wavelength
range. Optional mode transformers monolithically incorporated using Quantum Photonics’ patented Passive Active Resonant
Coupler (PARC) integration technology provide nearly circular output beam characteristics. This unique combination of ridge
waveguide laser design and integrated mode transformer make this device an ideal high-power optical source for eye-safe laser
transmitter applications.
FEATURES
▲MQW optimized for C-band or L-band laser wavelengths
▲High output power 200 mW InP ridge waveguide laser diode design
▲Integrated mode transformer for circular output beam pattern
▲Numerous packaging options including C-mount, CT-mount, chip-on-submount (CoS), TO-can, 14-pin butterfly, and bare die
APPLICATION
▲Optical source for free space optical wireless systems
▲Laser transmitter for eye-safe remote sensing applications
▲High-power external cavity semiconductor lasers
