[IEEE 2018 Asia Communications and Photonics Conference (ACP) - Hangzhou (2018.10.26-2018.10.29)] 2018 Asia Communications and Photonics Conference (ACP) - All-optical Phase Shifter and Switch Based on Microfiber Coated with Colloidal Quantum Dots

摘要： We propose an all-optical phase shifter and switch based on a microfiber coated with colloidal quantum dots, phase shift up to 5.95π is achieved, and the pump-controlled optical switch has an extinction ratio of 13dB.
