Using a high-Q Kerr-nonlinear SiN microresonator as a frequency comb source we generate a 1.44 Tbit/s (20×18 GBd PDM-QPSK) data stream and transmit it over 300 km. The comb is stabilized by a feedback control.
A high-Q SiN microresonator is used for the first time as an optical source for WDM transmission with advanced modulation formats. We transmit QPSK and 16QAM signals with a total bit rate of 392 Gbit/s.
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.
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.
Mid and near-IR optical frequency combs generation in ultra high Q crystalline and integrated SiN microcavities is presented. Moreover, universal dynamics that influences phase noise is described.
A nonlinear high-Q SiN microresonator is used as a frequency comb generator for data transmission at 170.8 Gbit/s. The main sources for signal impairment are identified. Further dispersion engineering is crucial for Terabit/s transmission.
Ultra-high-Q whispering gallery mode (WGM) resonators, with the ability to confine and store optical energy in small volumes enable optical frequency comb generation via four-wave mixing (FWM) [1] as first demonstrated in fused silica microtoroids [2,3]. In contrast to fused silica, resonators made from crystalline materials [4–9] such as CaF2, MgF2 and quartz feature exceptionally low loss over a...
We demonstrate frequency comb generation via four-wave-mixing in crystalline MgF2 whispering-gallery mode resonators. More than 800 comb lines spaced by 43 GHz are observed. Second order autocorrelation is performed for time-domain characterization.
Enhancement of 300times in third harmonic generation conversion efficiency for ultrafast laser pulses in gases is demonstrated. The enhancements are obtained by generating a spatially-localized plasma in the focal region of an ultrashort pulse.
We observe rotational wave packet dynamics in CO2 through third harmonic generation (THG). The conversion efficiency of THG is modulated by the wavepacket through ultrafast perturbations to linear and third-order optical susceptibilities.

We demonstrate propagation of ultrafast laser pulses through a molecular gas acting as a transient wave plate under conditions of strong phase modulation. A single, linearly polarized pulse is split into two distinct laser pulses.
Transient susceptibility tensors produced by rotational wavepackets formed by femtosecond laser pulses with arbitrary polarization are shown to be biaxial or uniaxial. Single-shot measurements of the phase modulation of a probe pulse are demonstrated.
Ultrafast lasers pulses are shaped when propagating through ultrafast index transients by controlling both the input pulse temporal phase and the index transient. This technique extends beyond the limits of standard pulse shapers
