The 4-Port Polarization Maintaining Optical Circulator is a compact, high performance lightwave component that routes incoming signals from Port 1 to Port 2, incoming Port 2 signals to Port 3, and incoming Port 3 signals to Port 4. This PM Optical Circulator provides high isolation, low insertion loss, high extinction ratio, and excellent environmental stability.
AFR broadband phase modulator combines high linearity with low driving voltage and small footprint, covering frequency range from DC up to 8 GHz. The extended operating temperature range given by this series of phase modulators can operate at different environmental applications.
AFR's LaseGuard Isolator Series is designed for guarding the laser from back reflected light. The isolator normally rotates the polarized plane 45° clockwise in the forward direcition, an λ/2 waveplate is an option if other output polarization is preferred. The high transmission efficiency, high isolation, high power handling ability and large aperture features make it flexible to fit different applications in laser protection.
The 1064 nm In-Line Polarizer is designed to pass light with one specific polarization while blocking the other polarization. It can be used to convert unpolarized light into polarized light with high extinction ratio. It can also be used to enhance the extinction ratio of signals with its excellent polarization properties. It is ideal for high speed communication systems and test instruments where high polarization extinction ratio is required.
The High Power Polarization Insensitive Circulator is characterized with low insertion loss, high isolation, high power handling, high return loss. This circulator is ideal for fiber lasers and instrumentation applications.
