Microresonator-based optical frequency comb (microcomb) has the potential to revolutionize the accuracy of frequency synthesizer in radar and communication applications. However, fundamental limit exists for low noise microcomb generation, especially in low size, weight, power and cost (SWaP-C) package. Here we resolve such low noise challenge to operate a microcomb close to its low quantum noise limit, in a direct-diode-pump and thus low SWaP-C setup. Such result is triggered by using fiber…

Low-pump-power, low-phase-noise, and microwave to millimeter-wave repetition rate operation in microcombs.

It is shown that a class of resonators having surface-loss-limited Q factors can operate over a wide range of repetition rates with minimal variation in threshold power, and a new, surface- loss-limited resonator illustrates the idea.
