    • Astrocombs: Recent Advances 

      Herr, T.; McCracken, R. A. (2019)
      Precision calibration of astronomical spectrographs is essential to the hunt for exoplanets, the study of cosmology and determining variation of the fundamental constants. Frequency combs (‘astrocombs’) can serve as ...
    • Compact, UAV compatible 2D Spectrometer for multi-species atmospheric gas analysis 

      Gouman, J.; Renevey, P.; Dasen, S.; Chin, S.; Herr, T.; Buchs, G.; Lütolf, F.; Lecomte, S.; Vergara, G.;  Martin, H.; Moselund, P. M.; Harren, F. J. M.; Balet, L. (2019)
      We present an UAV compatible spectrometer designed for sampling air pollutants in remote locations. Relying on a custom-made Multi-Pass Cell and a 3-5 µm broadband supercontinuum light source, it takes advantage of an ...
    • Dissipative Kerr Solitons in Optical Microresonators 

      Herr, T.; Gorodetsky, M. L.; Kippenberg, T. J. (2016)
    • In-Fibre Fabry-Perot Microresonator with 100 Million Q-Factor 

      Obrzud, E.; Lecomte, S.; Herr, T. (2017)
      A single-mode, 100 million Q-factor, Kerr-nonlinear Fabry-Perot microresonator with 10 GHz free-spectral range is fabricated. The resonator''s group velocity dispersion, coupling ratio and nonlinearity can be engineered ...
    • Mode spectrum and temporal soliton formation in optical microresonators 

      Herr, T.; Brasch, V.; Jost, J.D.; Mirgorodskiy, I.; Lihachev, G.; Gorodetsky, M.L.; Kippenberg, T.J. (2014)
      The formation of temporal dissipative solitons in optical microresonators enables compact, high-repetition rate sources of ultrashort pulses as well as low noise, broadband optical frequency combs with smooth spectral ...
    • Photonic chip based optical frequency comb using soliton induced Cherenkov radiation 

      Brasch, V.; Geiselmann, M.; Herr, T.; Lihachev, G.; Pfeiffer, M.H.P.; Gorodetsky, M.L.; Kippenberg, T.J. (2015)
      Microresonator optical frequency combs have become an actively researched alternative way to generate optical frequency combs. Their key properties are large mode spacings and the potential for photonic integration which ...
    • Properties of Broadband Soliton Microcombs in Pulse-Driven Integrated Microresonators 

      Anderson, M.; Bouchand, R.; Liu, J.; Obrzud, E.; Herr, T.; Kippenberg, T. J. (2019)
      Recently, pulse-driving of nonlinear microresonators, as opposed to continuous-wave driving (CW), has been demonstrated as a powerful method for overcoming the fundamental inefficiency of single-state dissipative Kerr ...
    • Spontaneous polarization symmetry breaking of light in a microresonator 

      Moroney, N.; Del Bino, L.; Woodley, M. T. M.; Zhang, S.; Hill, L.; Wittwer, V. J.; Südmeyer, T.; Wildi, T.; Oppo, G.-L.; Vanner, M.; Brasch, V.; Herr, T.; Del'Haye, P. (2021)
    • Temporal Dissipative Solitons in a Microresonator Driven by Optical Pulses 

      Obrzud, E.; Lecomte, S.; Herr, T. (2017)
      A nonlinear optical microresonator is driven by picosecond laser pulses resulting in formation of temporal dissipative solitons. These femtosecond solitons are stable and generated at a fraction of the power required in ...
    • Temporal solitons in optical microresonators 

      Herr, T.; Brasch, V.; Jost, J.D.; Wang, C. Y.; Kondratiev, N.M.; Gorodetsky, M.L.; Kippenberg, T.J. (2014)
      Temporal dissipative solitons in a continuous-wave laser-driven nonlinear optical microresonator were observed. The solitons were generated spontaneously when the laser frequency was tuned through the effective zero detuning ...
    • Universal dynamics and noise of Kerr-frequency combs in microresonators 

      Herr, T.; Hartinger, K.; Riemensberger, J.; Wang, C.Y.; Gavartin, E.; Holzwarth, R.; Gorodetsky, M.L.; Kippenberg, T.J. (2012)
      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 ...
