Broadex Technologies' Athermal Arrayed Waveguide Grating (Athermal AWG) is a fully passive device that requires no electrical power for thermal stabilization and are ideally suited for use in applications where no power is available. The Athermal AWG utilizes silica on silicon PLC technology to multiplex or de multiplex up to 96 wavelengths for DWDM bandwidth multiplication over a single fiber. Broadex Technologies offers a full line of MSA compatible Athermal AWGs with channel spacings of 50GHz, 75GHz, 100GHz, and 150GHz, covering the O,C, L and E Bands; and the devices are optimized for use in Central Office temperature applications (c temp) and or Remote Node temperature applications (i temp).

The Mach Zender Interferometer (MZI) technology transforms the performance of AWGs and provides the combines the best advantages of different AWG types: the lowest insertion loss of Gaussian AWGs with the wide and flat passband shape of Flat Top AWGs. This groundbreaking design enhancement provides 2 3dB insertion loss improvement over Flat Top AWGs while allowing for cost effective system components with the flat top passband shape and can be applied to all AWG types whether: flat top, cyclic and ultra wideband.
