The Polarization Beam Combiner/Splitter is a compact high performance lightwave component that combines two orthogonal polarization signals into one output fiber. The most common application is to combine two pump lasers into one single fiber to double the pump power in EDFA or Raman Amplifier. This Beam Combiner/ Splitter can also be used as a beam splitter.
AFR's Integrated Polarization Maintaining Tap Power Detector (PMTAPD) integrates the functionality of a optical coupler and a photodiode for optical network's power detection. It applys for channel power monitoring in DWDM system, in-line optical network switchingprotection monitoring(OLP), re-configurable optical add/drop multiplexer(OADM), and gain/attenuation monitoring in EDFA, etc.
AFR's MEMS Variable Optical Attenuator is based on an electrostatic drived micro-electro-mechanical-system (MEMS) chip. The MEMS Variable Optical Attenuator chip consists of a tilting mirror to change light coupling between input and output fibers. The components are characterized with low insertion loss, fast response and compact size. The MEMS Variable Optical Attenuator is widely uesd in WDM networks, power control or gain variation in EDFA.
The Gain Flattening Filter is a micro optics device based on environmentally stable thin-film filter technology. It is used to flatten the spectral gain in EDFAs. The components are characterized with low error function, low insertion loss, high return loss, excellent environmental stability and high power handling capability.
