The Reduced Cladding 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 instrumentations where high polarization extinction ratio is required.
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.
AFR's Thin-Film LiNbO3 intensity modulators that expand the performance of traditional LiNbO3 modulators combining much lower driving voltage and smaller footprint while extending the bandwidth above 65 GHz. The increasing demand to shift the transmission frequency in analog fiber optic links towards higher frequency finds in AFR analog modulators the most advanced and suitable answer. The experience and know-how of AFR engineers is available to customize our products to the customer's specific requirements.
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.
