High Q

We designed High-Q micro-ring resonators based on SOI material. A new method of using a top SiO2 layer to cover the waveguide is applied and the tested Q factor is as high as 1.0135×104. Micro-ring resonator has been fabricated using Electron-Beam Lithography and Inductive Coupled Plasma. OptiFDTD was used to simulate the micro-ring resonator and we compared the transmission spectrum of this resonator with the resonator without SiO2 covering.

Reduced Complexity

We report a broadband radio frequency (RF) channelizer with up to 92 channels using a coherent microcomb source. A soliton crystal microcomb, generated by a 49 GHz micro-ring resonator (MRR), is used as a multi-wavelength source. Due to its ultra-low comb spacing, up to 92 wavelengths are available in the C band, yielding a broad operation bandwidth. Another high-Q MRR is employed as a passive optical periodic filter to slice the RF spectrum with a high resolution of 121.4 MHz. We experimentally achieve an instantaneous RF operation bandwidth of 8.08 GHz and verify RF channelization up to 17.55 GHz via thermal tuning. Our approach is a significant step towards the monolithically integrated photonic RF receivers with reduced complexity, size, and unprecedented performance, which is important for wide RF applications ranging from broadband analog signal processing to digital-compatible signal detection.
