Arrayed Waveguide Gratings – AWG

What is an arrayed waveguide grating? An arrayed waveguide grating (AWG) is a device, typically built as a planar lightwave circuit, that can separate or combine optical signals of different wavelengths.

Arrayed waveguide grating

Arrayed waveguide gratings (AWG) are commonly used as optical (de)multiplexers in wavelength division multiplexed (WDM) systems. These devices are capable of multiplexing many wavelengths into a single optical fiber, thereby increasing the transmission capacity of optical networks considerably. The devices are based on a fundamental principle of optics, which states that light waves of different wavelengths do not interfere linearly with each other. This means that, if each channel in an optical communication
