In this paper, the performance of an on-chip hollow-core-waveguide (HW) using high-contrast gratings (HCG) for analog signal transmission is analyzed numerically. Simulation results indicate that after propagating 100 m in a HCG-HW with optimally designed parameters, there is very little degradation of either third-order intermodulation distortion spur-free dynamic range (IM3 SFDR) or third-order...
On-chip analog signal performance of high-contrast-grating hollow-core-waveguide is evaluated. SFDR of >;100 dB can be achieved for IM3 over a wide RF frequency range of 80 GHz and optical wavelength band of 50 nm after a 100-m propagation. An optimal waveguide design can produce analog performance comparable to optical fibers, which is dramatically better when compared with integrated low-loss...
A chip-scale hollow-core waveguide using high-contrast grating yields slow light with a group velocity <0.02c and loss as low as 0.2dB/cm over 50GHz bandwidth. Loss and group velocity are independently optimized for the first time.
