The Polarization Maintaining Filter Wavelength Division Multiplexer provides wavelength division multiplexing (or demultiplexing) while maintaining signal polarization. The components are based on environmentally stable thin-film filter technology and are characterized with high extinction ratio, low insertion loss, and high return loss. They are ideal for high speed WDM network systems.
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.
The Filter Wavelength Division Multiplexer is based on environmentally stable thin-film filter technology. The devices combine or separate light at different wavelengths in a wide wavelength range. The FWDM offers very low insertion loss, low polarization dependence, high isolation and excellent environmental stability. High power handling capability can be achieved through unique pigtail processing and high quality AR coating. These components have been extensively used in EDFAs, Raman amplifiers, WDM networks and fiber optical instruments.
The Multimode Fiber Bandpass Filter is a micro optic device based on environmentally stable thin film filter technology. It is used to block out unwanted noise signals in multimode fiber communication systems. These components are characterized with high isolation, low insertion loss, high return loss, excellent environmental stability and high power handling capability.
The ClearCut 2 μm Series Fiber Bragg Grating products are ultra low insertion loss fiber bragg gratings for high power fiber lasers. With AFR's ClearCut design and special process, the FBG can handle high power laser around 2 μm. Custom configurations are available.
