Abstract
We report the design and numerical analysis of a tellurium oxide rib waveguide pumped with femtosecond laser pulses at 1550 nm for near and mid-infrared wavelength conversion at 0.96 and 4.05 μm, respectively. The wavelength conversion principle is based on the degenerate four-wave mixing in the designed tellurium oxide rib waveguide device. The corresponding detuning in the frequencies is as large as �120 THz at both sides of the pump frequency. This is the largest detuning of the frequencies obtained using a TeO2 rib waveguide via a four-wave mixing process to the best of our knowledge. Such waveguide-based light sources are required for various potential applications, including chemical sensing, absorption spectroscopy, and generation of quantum correlated photons on future nonlinear photonic integrated circuits. © 2021 Author(s).
