Low-loss tantalum pentoxide photonics with a CMOS-compatible process Open
We report a Ta 2 O 5 photonic platform with a propagation loss of 0.49 dB/cm at 1550 nm, of 0.86 dB/cm at 780 nm, and of 3.76 dB/cm at 2000 nm. The thermal bistability measurement is conducted in the entire C-band for the first time to rev…

Investigation of <i>χ</i> <sup>(2)</sup>-Translated Optical Frequency Combs Tunability in Gallium Phosphide-on- Insulator Resonators Open
We describe a synergistic optimization approach that enables highly efficient frequency translation of a Kerr optical frequency comb (OFC) from 1550 nm to 775 nm in a gallium phosphide-on-insulator (GaP-OI) microresonator. Key distinctions…

Design of Partially Etched GaP-OI Microresonators for Two-Color Kerr Soliton Generation at NIR and MIR Open
We present and theoretically investigate a dispersion engineered GaP-OI microresonator containing a partially-etched gap of 250 nm x 410 nm in a 600 nm x 2990 nm waveguide. This gap enables a 3.25 μm wide anomalous dispersion spectral span…
