Abstract
Four-wave mixing (FWM) offers promising applications in wavelength conversion, optical signal processing, and even quantum photonics. We report a study of stimulated FWM in a Q-InP channel waveguide fabricated at a commercial foundry (SMART Photonics). We performed FWM experiments and observed a nearly flat wavelength-conversion efficiency of -56.5 dB over a wide detuning range. This is attributed to the broadspectrum phase matching resulting from the small interaction length of 0.564 mm. The low-power pump and signal wavelengths are employed in these measurements to minimise absorption effects, such as two-photon absorption (TPA). Our results demonstrate that InP has high potential for nonlinear processes that require lower input power, such as spontaneous four-wave mixing (SFWM) for single-photon generation.
