Harnessing Giant Brillouin Gain for Advanced Integrated Microwave Signal Processing
Abstract
Several major achievements are: 1. Onchip processing of optical signals using Brillouin scattering demonstrated for highcapacity communications 2. Worldrecord onchip Brillouin gain of 52 dB with net gain of 47 dB 3. Multiple simultaneous notch responses demonstrated using the SBS chip. The current maximum number of notches is 3 4. Onchip True time delay demonstrated 5. Concept of phase amplification employed to amplify the phase by 10 times. 6. A microwave photonic processor capable of phase shift, delay and filtering demonstrated 7. We combined silicon nitride technology with fibrebased SBS to demonstrate a lossless RF photonic notch filter 8. We used silicon nitride technology to demonstrate an onchip alloptimized filter 9. Using silicon nitride technology we demonstrated a delay line with a tuning speed >1 GHz 10. Dr Eric Magi visited the US Army Research Lab in Adelphi, Maryland in early 2017 to demonstrate the Microwave photonic filter prototype filter to key stakeholders from the US defence sector. Total of 12 published papers, 13 invited talks, and received additional funding from AUD.
