Abstract

Optical parametric amplifiers relying on the nonlinear four-wave mixing process have attracted much interest in optical communication, ultrafast signal processing, and quantum metrology. Here, we propose a dual-pump optical parametric amplifier based on a bilayer silicon-rich nitride waveguide with flattened dispersion. The amplifier can possess a high gain of 26.2 dB and a low wavelength-dependent gain ripple of 1 dB over a more-than-400-nm wavelength range. We also examine the amplification of an ultrashort soliton pulse with a peak power of 0.25 W and a pulse width varying from 7 to 20 fs. The gain can reach 19 dB, which is suitable for boosting low-energy broadband sources.
