Arrayed waveguide grating wavelength division

Arrayed waveguide gratings (AWG) are commonly used as optical (de)multiplexers in wavelength division multiplexed (WDM) systems. A grating with a diffraction order of 20 has been fabricated using a composite glass waveguide. 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. g and dispersive properties. AWGs were first reported by Smit (1988) and later by. This application note describes how to design, simulate and layout an Arrayed Waveguide Grating (AWG) using OlympIOs. [pdf]
