We demonstrate a high-Q RF transversal filter based on a 49GHz-FSR integrated microcomb source that provides 80 taps across the C-band. By employing an on-chip micro-ring resonator, we generate a broadband Kerr comb with a large number of comb lines and use it as a high-quality multi-wavelength source. A Q factor of 73.7, an out-of-band rejection of 48.9 dB, and a wide tunable range are demonstrated. The experimental results verify the feasibility of our approach as a solution towards implementing highly reconfigurable MPFs with a large tap number and reduced system complexity.Keywords: Radio frequency photonics, nonlinear optics, integrated optics

AbstractBy providing an effective way to leverage nonlinear phenomena in integrated devices, high-Q optical resonators have led to recent advances in on-chip photonics. However, developing fabrication processes to shape any new material into a resonator with extremely smooth surfaces on a chip has been an exceptionally challenging task. Here, we describe a universal method to implement ultra-high-Q resonators with any new material having desirable properties that can be deposited by physical vapor deposition. Using this method light-guiding cores with surface roughness on the molecular-scale are created automatically on pre-patterned substrates. Its efficacy has been verified using As2S3, a chalcogenide glass that has high-nonlinearity. The Q-factor of the As2S3 resonator so-developed approached the propagation loss record achieved in chalcogenide fibers which were limited by material losses. Owing to the boosted Q-factor, lasing by stimulated Brillouin scattering has been demonstrated with 100 times lower threshold power than the previous record.

Important Design

In this work, on-chip spiral inductors with back hollow structure have been prepared on the 500 [Formula: see text] thick silicon substrate with high resistivity [Formula: see text]. The silicon underneath the inductor region has been completely etched by deep etching process in order to reduce the substrate eddy current losses. Several types of square spiral on-chip inductors with different metal width (w) and line spacing (s) in the case of [Formula: see text] were fabricated. The experimental results are verified by FEM simulation using HFSS software. The results show that the Q-factor and self-resonance frequency of back hollow structure inductors are both enhanced compared with the conventional inductors. Furthermore, narrower width of coils for the on-chip spiral inductors with back hollow structure can result in higher Q-factor, inductance L and self-resonance frequency, which provide some important design guides for the fabrication of the high performance on-chip inductors.

A high-Q-factor tunable silica-based microring resonator (MRR) is demonstrated. To meet the critical-coupling condition, a Mach–Zehnder interferometer (MZI) as the tunable coupler was integrated with a racetrack resonator. Then, 40 mW electronic power was applied on the microheater on the arm of MZI, and a maximal notch depth of about 13.84 dB and a loaded Q factor of 4.47 × 106 were obtained. The proposed MRR shows great potential in practical application for optical communications and integrated optics.
