Summary: This study experimentally investigates the generation of controllable frequency comb in the microwave range, using a tunable superconducting coplanar-waveguide resonator. The central frequency and teeth density of the comb can be precisely controlled, and the number of sidebands can be increased with drive power. The minimum drive power required to generate the comb approaches the quantum limit.

Summary: We demonstrate the generation of optical frequency comb in a tellurite microsphere, which is the first time for tellurite glass microresonators. The TeO2-WO3-La2O3-Bi2O3 (TWLB) glass microsphere has a record-breaking Q-factor of 3.7 x 107 among tellurite microresonators. By pumping the microsphere with a diameter of 61 μm at a wavelength of 1.54 μm, we obtain a frequency comb with seven spectral lines in the normal dispersion range.

Summary: Pump powers were investigated for their influence on silicon microresonator-based Kerr comb generation, showing that low pump powers and reverse bias are essential for efficient comb spectrum. Increasing pump powers can suppress Kerr comb generation and produce similar comb lines as low pump powers under certain conditions.

Summary: Efficient generation of mid-infrared frequency combs is demonstrated based on continuous-wave-seeded femtosecond optical parametric generation in nonlinear waveguides. The conversion efficiency of the near-infrared pump to signal and idler light is high, with exceptionally low relative intensity noise in the mid-infrared comb. Additionally, the mid-infrared bandwidth can be increased by driving the process with a broadband pump obtained via supercontinuum generation.

Summary: This article proposes a novel scheme for generating optical frequency combs using a three-stage generator, involving optical injection-induced dynamics, subharmonic electro-optic modulation, and four-wave mixing. The comb characteristics can be easily adjusted by tuning the seed OFC spacing and subharmonic electro-optic modulation, leading to stable comb generation. Additionally, the optical spectrum can be broadened through the FWM process, demonstrating robust OFCs with specific comb spacing and teeth numbers in experiments.

Summary: In this paper, the frequency comb response in a rhombic micro-resonator with parametrical modulation is experimentally and analytically studied. The results show that by modulating the micro-resonator axially with a low-frequency periodic excitation, a comb-like vibration response with equidistantly positioned fingers in the frequency domain can be achieved. The finger spacing of the frequency comb response is consistent with modulation frequency, and the number and amplitude of the fingers can be tuned by modulation strength. Additionally, when the resonator is simultaneously modulated by two different low-frequency excitation signals, a mixed frequency comb with extra comb fingers is generated, and unequal spacing frequency combs can be achieved for more flexible tunability of the comb spacing.
