WebWith the optical Q -factor of the MBR modes being greater than 10 7, four-wave mixing is observed at 765 nm for a pump power of 3 mW. By increasing the pump power, parametric oscillation is achieved, and a frequency comb with 14 comb lines is generated at visible wavelengths. © 2016 Optical Society of America Full Article PDF Article WebOct 12, 2024 · Optical parametric oscillation (OPO) in a microresonator is promising as an efficient and scalable approach to on-chip coherent visible light generation. However, so far, only red light near the edge of the visible band at 710 nm has been reported. In this work, we demonstrate on- chip OPO covering >130 THz of the visible spectrum, including ...
Photon–phonon parametric oscillation induced by quadratic …
The OPO consists essentially of an optical resonator and a nonlinear optical crystal. The optical resonator serves to resonate at least one of signal and idler waves. In the nonlinear optical crystal, the pump, signal and idler waves overlap. The interaction between these three waves leads to amplitude gain for signal and idler waves (parametric amplification) and a corresponding deamplification of the pump wave. The gain allows the resonating wave(s) (signal or idler or bot… A parametric oscillator is a driven harmonic oscillator in which the oscillations are driven by varying some parameter of the system at some frequency, typically different from the natural frequency of the oscillator.
