AFR high bandwidth zero-chirp F10 modulators are based on the Mach-Zehnder Interferometer (MZI) architecture. They are manufactured using the highly reliable titanium indiffusion technology in X-Cut, Y-Propagating LiNbO3 substrates. The F10 is a single drive modulator designed for high bit rate advanced metro to long haul communication systems that requires the superior performance. The F10 modulator contains an integrated photo detector that may be used to set and lock the DC bias on the modulator as well as provide an estimate of the modulator output optical power.
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 40G-Thin Film modulator design is based on a dual parallel structure of 2 Mach-Zehnder modulators embedded in a Mach-Zehnder super-structure. Each internal modulator is designed to have EO bandwidth above 20 GHz. Monitor photodiode is provided for automatic bias control.
The High Power Polarization Maintaining Isolator is characterized with low insertion loss, high isolation, high power handling, high return loss, excellent environmental stability and reliability. This optical isolator is ideal for fiber laser and instrumentation applications.
