AWG Wavelength Division Multiplexer Intelligent Type Performance Comparison and Selection Guide
Here, we develop a novel design approach that co-optimizes inverse-designed wavelength division multiplexers and distributed Bragg gratings to achieve ultra-low crosstalk without compromising insertion loss. Current solutions are limited by trade-offs between channel spacing, crosstalk, insertion. This paper addresses the design of arrayed waveguide grating (AWG) devices from the viewpoint of -3dB bandwidth and free spectral range. 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.
