Integrated solutions for optical orbital angular momentum multiplexed transceiver
Final Report Abstract
This project aimed to develop integrated optical OAM multiplexed transceivers to enhance optical communication system capacity. Despite challenges, including funding reduction and collaboration constraints due to the pandemic and geopolitical tensions, the project achieved significant milestones. The key findings include: Rectangular dielectric waveguides can efficiently transmit low-order OAM states, but higher-order modes require optimization due to phase mismatches and mode purity degradation. • An innovative approach was developed to enhance inter-chip and intra-chip data transmission speeds, enabling secure on-chip hardware-to-hardware optical communication. • Multimode waveguides show potential as low-loss components for on-chip communication systems, supporting higher-order OAM mode transmission on a silicon interposer. These results demonstrate the potential for robust, scalable, and energy-efficient OAM- based solutions in short-range optical communications, with applications in quantum information transfer, material microscopy, and health monitoring sensors. The project's findings pave the way for future advancements in OAM multiplexed transceivers and the miniaturization of optical communication systems, addressing the "capacity crunch" in fiber optic communications.
