Pushing the limits of CMOS optical parametric amplifiers with USRN:Si7N3 above the two-photon absorption edge
Typical CMOS materials in the telecommunications band suffer from two-photon absorption or possess weak Kerr nonlinearities. Here, Ooiet al. demonstrate 42.5 dB optical parametric amplification in ultra-silicon-rich nitride waveguides, designed to have strong nonlinearities with negligible losses.
