Experimental demonstration of on-chip optical parametric oscillation in planar tantalum pentoxide waveguides
Tantalum pentoxide ( ) planar waveguides have recently been shown to possess unusually large nonlinearities, and nonlinear Kerr coefficient ( ), leading to potential applications in nonlinear integrated optics, such as supercontinuum generations and optical parametric oscillations.

When pumped at wavelength of 800 nm, the waveguides show parametric conversions when seeded in the near infra-red (IR) that results to strong signals in the visible spectrum. We report in this paper the detailed experiment procedures seeding the parametric process in the telecoms range of 1200 to 1600 nm and experimentally demonstrate the parametric output wavelengths in the visible (533 to 600 nm). The observed non-linearities demonstrate the potential of tantalum pentoxide in incorporating optical parametric processes on a chip.

Abstract

Tantalum pentoxide ( ) planar waveguides have recently been shown to possess unusually large nonlinearities, and nonlinear Kerr coefficient ( ), leading to potential applications in nonlinear integrated optics, such as supercontinuum generations and optical parametric oscillations. In this paper, we report the first experimental demonstration of a third-order susceptibility ( ) governed nonlinear optical parametric process within 7 mm long planar tantalum pentoxide waveguide by using a pump-probe configuration. When pumped at wavelength of 800 nm, the waveguides show parametric conversions when seeded in the near infra-red (IR) that results to strong signals in the visible spectrum. We report in this paper the detailed experiment procedures seeding the parametric process in the telecoms range of 1200 to 1600 nm and experimentally demonstrate the parametric output wavelengths in the visible (533 to 600 nm). The observed non-linearities demonstrate the potential of tantalum pentoxide in incorporating optical parametric processes on a chip.
