Coherent Control of Mid-Infrared Frequency Comb by Optical Injection of Near-Infrared Light
Kenichi N. Komagata, Alexandre Parriaux, Mathieu Bertrand +5
We demonstrate the use of a low power near-infrared laser illuminating the front facet of a quantum cascade laser (QCL) as an optical actuator for the coherent control of a mid-inf…
Synchronization of frequency combs by optical injection
Johannes Hillbrand, Mathieu Bertrand, Valentin Wittwer +8
Optical frequency combs based on semiconductor lasers are a promising technology for monolithic integration of dual-comb spectrometers. However, the stabilization of the offset fre…
Dissipative Kerr solitons in semiconductor ring lasers
Bo Meng, Matthew Singleton, Johannes Hillbrand +3
Dissipative Kerr solitons are self-organized optical waves arising from the interplay between Kerr effect and dispersion. They can form spontaneously in nonlinear microresonators p…
Controlling Quantum Cascade Laser Optical Frequency Combs through Microwave Injection
Barbara Schneider, Filippos Kapsalidis, Mathieu Bertrand +4
In this work, control over the precise state emitted by quantum cascade laser frequency combs through strong radio-frequency current modulation close to their repetition frequency…
Engineering the spectral bandwidth of quantum cascade laser frequency combs
Maximilian Beiser, Nikola Opačak, Johannes Hillbrand +2
Quantum cascade lasers (QCLs) facilitate compact optical frequency comb sources that operate in the mid-infrared and terahertz spectral regions, where many molecules have their fun…
Frequency comb generation by Bloch gain induced giant Kerr nonlinearity
Nikola Opačak, Sandro Dal Cin, Johannes Hillbrand +1
Optical nonlinearities are known to provide a coherent coupling between the amplitude and phase of the light, which can result in the formation of periodic waveforms. Lasers that e…
Mode-locked ultrashort pulses from an 8 m wavelength semiconductor laser
Johannes Hillbrand, Nikola Opacak, Marco Piccardo +4
Quantum cascade lasers (QCL) have revolutionized the generation of mid-infrared light. Yet, the ultrafast carrier transport in mid-infrared QCLs has so far constituted a seemingly…
In-phase and anti-phase synchronization in a laser frequency comb
Johannes Hillbrand, Dominik Auth, Marco Piccardo +5
Coupled clocks are a classic example of a synchronization system leading to periodic collective oscillations. This phenomenon already attracted the attention of Christian Huygens b…
A monolithic frequency comb platform based on interband cascade lasers and detectors
Benedikt Schwarz, Johannes Hillbrand, Maximilian Beiser +6
Optical frequency combs enable all-solid-state spectrometers that will trigger a breakthrough in miniaturization and on-chip integration of mid-infrared sensing technology. Interba…
Coherent injection locking of quantum cascade laser frequency combs
Johannes Hillbrand, Aaron Maxwell Andrews, Hermann Detz +2
Quantum cascade laser (QCL) frequency combs are a promising candidate for chemical sensing and biomedical diagnostics, requiring only milliseconds of acquisition time to record abs…
