A micro lens was formed at the end of fiber to couple with active chips in LD and PD modules. Conical and wedge lensed fiber are both available, other shapes can be customized. And AFR can provide one stop service for fiber tail assembly, including lensed fiber, fiber metallization, AR-coating, feedthrough soldering, fiber connectorization, etc.
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.
The ClearCut 2 μm Series Fiber Bragg Grating products are ultra low insertion loss fiber bragg gratings for high power fiber lasers. With AFR's ClearCut design and special process, the FBG can handle high power laser around 2 μm. Custom configurations are available.
The High Power Polarization Insensitive Isolator is characterized with low insertion loss, high isolation, high power handling, high return loss, excellent environmental stability and reliability. This fiber isolator is ideal for fiber lasers and instrumentation applications.
The Unidirectional Integrated Tap Photodiode (UTPD) integrates the functionality of an optical coupler and a photodiode for optical network's power detection. The unidirectional feature allows the PD to respond to power from input port only. It can be applied for channel power monitoring in DWDM system, in-line optical network switching protection monitoring (OLP), reconfigurable optical add/drop multiplexers (ROADM), and gain/attenuation monitoring in EDFAs, network's power detection, etc.
