Abstract

All-optical processing and generation are regarded as a key solution to achieve ultrahigh bitrate communication in next generation. Silicon based optical waveguides have been widely developed, including ultrafast electrical-optical modulator, splitter, wavelength generator, and etc. However, the carrier relaxation issues as well as inevitable two-photon absorption in communication regions limit its application in developing ultrafast all-optical modulation and supercontinuum generation. Recently, large optical bandgap materials have been utilized to demonstrate nonlinear waveguide applications for all-optical processing. Tantalum pentoxide (Ta2O5) used to serve as gate dielectric and optical coatings in optoelectronic devices due to its high dielectric constant and refractive index properties. Nowadays, Ta2O5 with high optical nonlinearity and free of nonlinear absorption let it suitable in developing small footprint, high power operation optical devices [1, 2].
