Four-channel 1W Fiber-combined mid-wave infrared quantum cascade laser BQCLF-4600-01T-M
The BQCLF-4600-01T-M mid-infrared quantum cascade laser series provides four independently or simultaneously controlled channels through one output fiber. Advanced quantum-well epitaxy on an indium-phosphide substrate, a highly reliable ridge waveguide and a Fabry–Perot cavity are used. A gold-plated copper enclosure provides good thermal conductivity, and gold-plated electrodes provide good electrical conductivity. An internal 10kΩ thermistor measures temperature near the chip for the external temperature-control system. The 105μm-core output fiber has low bending loss and a standard SM905 termination.
