Mid-infrared optical frequency combs at 2.5 mu m based on crystalline microresonators

Tobias Kippenberg, Tobias Herr, Albert Schliesser

The mid-infrared spectral range (lambda similar to 2-20 mu m) is of particular importance as many molecules exhibit strong vibrational fingerprints in this region. Optical frequency combs-broadband optical sources consisting of equally spaced and mutually ...

Universal formation dynamics and noise of Kerr-frequency combs in microresonators

Tobias Kippenberg, Emanuel Gavartin, Tobias Herr

Optical frequency combs allow for the precise measurement of optical frequencies and are used in a growing number of applications. The new class of Kerr-frequency comb sources, based on parametric frequency conversion in optical microresonators, can comple ...

Universal Dynamics of Kerr-Frequency Comb Formation in Microresonators

Tobias Kippenberg, Emanuel Gavartin, Tobias Herr

We experimentally investigate the initial dynamics of Kerr-frequency comb formation in crystalline MgF2 and planar Si3N4 microresonator and present a universal, platform independent condition for low phase noise performance. ...

Dispersion engineering of thick high-Q silicon nitride ring-resonators via atomic layer deposition

Tobias Kippenberg, Tobias Herr, Victor Brasch

We demonstrate dispersion engineering of integrated silicon nitride based ring resonators through conformal coating with hafnium dioxide deposited on top of the structures via atomic layer deposition. Both, magnitude and bandwidth of anomalous dispersion c ...

Phase Noise and Dispersion in integrated Silicon Nitride based Kerr-Comb generators

Tobias Kippenberg, Emanuel Gavartin, Tobias Herr

We report on measurements of phase noise dynamics of microwave beat notes observed in low repetition rate silicon nitride based Kerr-comb generators and relate them to results from dispersion simulations and measurements. (C) 2011 Optical Society of Americ ...

Octave Spanning Tunable Frequency Comb from a Microresonator

Tobias Kippenberg, Emanuel Gavartin, Tobias Herr

We report the generation of an octave-spanning optical frequency comb in a continuous wave laser pumped microresonator. The generated comb spectrum covers the wavelength range from 990 to 2170 nm without relying on additional external broadening. Continuou ...
