Flexible Transmission Control of Mode Conversion and Application of Reconfigurable On-Chip Optical Tweezer

An optical mode converter with controllable coupling efficiency is designed using SWG with TiO2 cladding. The output can be tuning 0.05%-96.4% of input energy when the temperature rises 0–400 K. Prototype of on-chip reconfigurable optical tweezers demonstrated using multi-mode interference.
