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 Polarization Maintaining Fused Coupler offers very low insertion loss, high polarization extinction ratio and excellent environmental stability. Accurate coupling ratios from 0.01/99.99 to 50/50 are available with very good uniformity at center wavelength. These components find extensive applications to perform power splitting and mornitoring functions in all kinds of optical communication systems.
The 980/1550 IWDM series combines filter WDM and isolator into a compact package to offer cost saving solution. This device is ideal for fiber amplifier application to combine signal and pump wavelengths with very stable 1550 nm signal isolation. It is designed according to Telcordia standard and capable of high power handling.
The 1064 nm Polarization Maintaining Filter Coupler is manufactured by using advanced technology to allow the input signal to be split at various ratios with high extinction ratio.
