Kerr frequency comb generation in silicon nitride micro-ring resonators

Research output: Contribution to conferencePosterAcademic


Frequency comb generation in waveguide micro-ring resonators on a chip enables to realize compact, portable, and robust coherent sources with a large bandwidth span, finding use in various applications including precision spectroscopy, frequency metrology, and optical clocks. Essential properties for the resonator are a high quality factor and small mode volume to yield a low threshold, a dispersion engineered cross section to fulfill phase matching conditions, and appropriate optical laser excitation.
We demonstrate Kerr comb generation in micro-ring resonators fabricated from stoichiometric silicon nitride (Si3N4) with various ring diameters and coupling parameters [1]. We report on the dependence of the threshold and the generated comb spectrum on the quality factor of the resonator and pump power, respectively.
