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. This technique enables bidirectional communications over a. 📦 For purchasing, use the RP Photonics Buyer's Guide for wavelength division multiplexing. It provides an expert-curated supplier directory, buyer-focused technical background information, and structured selection criteria to support professional procurement decisions. Current solutions are limited by trade-offs between channel spacing, crosstalk, insertion.
