The Singlemode Wavelength Division Multiplexer combine or separate light at different wavelengths. They offer very low insertion loss, low polarization dependent loss, high isolation and excellent environmental stability. These components have been extensively used in raman amplifier, CATV, WDM networks and fiber optic instruments.
The Polarization Maintaining Filter Wavelength Division Multiplexer provides wavelength division multiplexing (or demultiplexing) while maintaining signal polarization. The components are based on environmentally stable thin-film filter technology and are characterized with high extinction ratio, low insertion loss, and high return loss. They are ideal for high speed WDM network systems.
The Gain Flattening Filter is a micro optics device based on environmentally stable thin-film filter technology. It is used to flatten the spectral gain in EDFAs. The components are characterized with low error function, low insertion loss, high return loss, excellent environmental stability and high power handling capability.
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 2 μm Polarization Maintaining Tap Coupler/Splitter is manufactured by using advanced technology to allow the input signal to be split at various ratios with high extinction ratio.
