- 요약An optical frequency comb (OFC) is a light source with a spectrum composed of a set of sharp lines with equal frequency spacing. The technology has developed rapidly with applications in atomic and frequency metrology, precision spectroscopy, ultrafast optics, and quantum information. With these advancements, the large size, weight, power consumption, and cost (SWaP-C) of such systems limited real-world applications in the field. In parallel, nano-fabrication technologies rapidly developed miniature, on-chip microresonators with Q factors greater than one million in a plethora of platforms including those with strong nonlinear parameters. With these microresonators, the first micro-frequency combs (microcombs) were developed and have become a rich field of study regarding nonlinear photonics. Significant efforts have been made to practically implement these microcombs into systems to reduce SWaP-C. In this dissertation, I focus on four of these different areas. First, generation of low phase noise microwave signals is achieved by utilizing a 1-THz microcomb. We create a novel technique for cancelling out the phase noise contributions from the RF source driving the electro-optic comb allowing for frep detection which has limited the phase noise of the microwave signal in prior work. The output is tunable without phase noise degradation. The carrier envelope offset fceo is also measured, opening the door to full comb self-referencing. Second, we utilize a 95-GHz chaotic microcomb to perform optical coherence tomography. The axial resolution surpasses that of a comparable superluminescent diode-based design, reaching 5.65 ±1.7-μm axial resolution. Third, we design a photonic integrated circuit for generating and carrying microwave signals on an optical pulse train to a cryogenic quantum system. The system reduces stringent requirements on the driving electronic equipment while reducing the heat load and maintaining configurability of the waveform. We demonstrate RF tone and pulse generation with a spurious-free dynamic range of 31- dB and long-term phase stability of 30-mrad standard deviation over a 36-hour measurement window, improving on a fiber implementation of the architecture by three orders of magnitude. Finally, we examine a dual-pumped microresonator for generating tunable optical parametric oscillations in an anomalous group-velocity dispersion cavity. We show gain competition exists between multiple parametric oscillation processes that exist different pump configurations and that switching behavior arises.
