  • Working principle of AWG Wavelength Division Multiplexer

    Working principle of AWG Wavelength Division Multiplexer

    Arrayed waveguide gratings (AWG) are commonly used as optical (de)multiplexers in wavelength division multiplexed (WDM) systems. These design of these devices are based on an. g and dispersive properties. AWG has filtering characteristics and versatility, which can obtain a large number of wavelengths and channels, to realize the multiplexing and demultiplexing. An arrayed waveguide grating is a (typically fiber -coupled) device which can separate or combine signals with different wavelengths. It is usually built as part of a planar lightwave circuit (photonic integrated circuit), where the light coming from an input fiber first enters a multimode.
