The Bandpass Filter is a micro optics device based on environmentally stable Thin-Film filter technology. It is used to block out unwanted noise signals in EDFAs and fiber laser systems. These components are characterized with high isolation, low insertion loss, high return loss, excellent environmental stability and high power handling capability.
AFR 1 × 2 PM MEMS Optical Switch 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, high return loss, excellent environmental stability and reliability. The optical switch has been widely used in fiber optics communication equipment, fiber instruments, fiber sensing to switch channels.
The ClearCut Raman Scattering Suppressor Fiber Bragg Grating products are ultra low insertion loss fiber bragg gratings for high power fiber lasers. With AFR's ClearCut designing and special process, the devices can handle kilowatt level pump power and signal power with recoated only. It is the only cost-effective solution that eliminates the SRS at its source and enables immunity from back reflection from the work piece.
The Polarization Maintaining Fused Wavelength Division Multiplexer combine or separate light at different wavelengths. They offer very low insertion loss, high extinction ratio, and excellent environmental stability. These components can be operated on both fast and slow axis.
