low photodarkening loss and high beam quality makes them ideal for compact fiber based power amplifiers
SPDC-1570-20-SP is a 20 mm length Periodically Poled Lithium Niobate (PPLN) waveguide chip designed to operate at 1570 nm
1550 nm PM Bandpass Filter,20 nm Pass Bandwidth, 30 nm Stop Bandwidth FBG Sensor The coupler is a 1x2The Bandpass Filter is a micro optics device based on environmentally stable thin film filter technology. It is widely applied to blocking the unwanted noise signals in EDFA and fiber pump laser systerms, to get the signals needed. The components are characterized with high isolation, low insertion loss, high return loss, excellent environmental stability and reliability and high power handing capability.
