Dual-polarization RF Channelizer Based on Kerr Soliton Microcomb Sources
Xingyuan Xu, David J. Moss
We report a dual-polarization radio frequency (RF) channelizer based on microcombs. With the tailored mismatch between the FSRs of the active and passive MRRs, wideband RF spectra…

Supercontinuum generation in dispersion engineered highly doped silica glass waveguides
Guangkuo Li, Yuhua Li, Feng Ye +6
We investigate the effect of a lower index oxide layer inclusion within a highly doped silica glass slot waveguide for optimized supercontinuum generation at telecom wavelengths. B…

Radio frequency spectrum analyzer with a 5 THz bandwidth based on nonlinear optics in a CMOS compatible high-index doped silica waveguide
Yuhua Li, Zhe Kang, Kun Zhu +8
We report an all-optical radio-frequency (RF) spectrum analyzer with a bandwidth greater than 5 terahertz (THz), based on a 50-cm long spiral waveguide in a CMOS-compatible high-in…
