Athermal AWGs (Flat-Top)

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).

In a flat top AWG, the passband shape of each channel is designed to be wider than a natural Gaussian passband shape as well as having a flat frequency response over the channel clear window. This increases the insertion loss but allows for more uniform behavior over temperature, reducing the tolerances required by lasers and filters in the system and enabling high overall system performance with lower cost.
