Abstract: The sub-terahertz (sub-THz) frequency range, 100–300 GHz, has garnered significant attention in the wireless communication community for its potential to meet the growing data rate demand.

Abstract: We demonstrate the first octave-spanning supercontinuum generation with a spectrum ranging $800-2200 ~\text{nm}$ from a sub-millimeter (sub-mm)-length gallium phosphide waveguide.
