Exploration of Single-Chip Phase-Sensitive Amplifiers
Abstract
A monolithically integrated photonic phase-sensitive amplification chip is fabricated and demonstrated for the first time based on an InP/InGaAsP platform. On the chip, two tunable laser pumps coherently injection-locked from sidebands of an external modulated tone are generated to enable signal-degenerate dual-pumped phase-sensitive amplification in a highly saturated semiconductor optical amplifier. Phase-sensitive amplification is experimentally achieved with approximately 6.3 dB and 7.8 dB extinction of phase-sensitive on-chip gain using two different chips. Theoretical simulations based on coupled differential equations are performed and agree well with experimental results. The noise figure of the phase-sensitive amplification chip is also estimated, and averaged noise figures ~ 2.4 dB are measured.
