  • Anti-tracking of AWG wavelength division multiplexers for wind power generation in the Gulf region

    Anti-tracking of AWG wavelength division multiplexers for wind power generation in the Gulf region

    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. WDM (Wavelength Division Multiplexing) technology is a technique used to increase the bandwidth and improve the transmission capacity of optical fibers by transmitting multiple optical signals of different wavelengths. TFF (Thin-Film Filter) and AWG (Arrayed Waveguide Grating) are two commonly used. Arrayed waveguide gratings (AWG) are commonly used as optical (de)multiplexers in wavelength division multiplexed (WDM) systems. 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.
