Athermal Cyclic AWGs

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 Athermal Cyclic AWG is a unique implementation of a normal AWG that reduces the width of the device free spectral range significantly in order to utilize the adjacent diffraction orders of a channel set. This allows the device to address channel sets in a bidirectional manner and use one set of channels for upstream data, and one set for downstream data. This dramatically reduces the number of PLC devices required and Cyclic AWGs are increasingly in demand for WDM PON applications. Broadex Technologies can also provide optional enhanced functionality that enables a device to operate over both the C and L bands.
