Abstract

Tantalum pentoxide (Ta2 O5 ) planar waveguides have recently been shown to possess unusually large nonlinearities, and nonlinear Kerr coefficient (n2 ), leading to potential applications in nonlinear integrated optics, such as supercontinuum generation. In this paper, we report the experimental demonstration of a third-order susceptibility (χ(3) ) governed nonlinear optical parametric process within a 7 mm long planar tantalum pentoxide waveguide using a pump-probe configuration. When pumped at 800 nm, and seeded in the near infra-red (IR) the waveguides allow parametric conversion giving rise to signal photons in the visible spectrum. By seeding the parametric conversion process in the 1200 to 1600 nm IR telecoms range, we obtain continuously tunable output over the visible range (533 to 600 nm) from a single guide.
