Theory of frequency modulated combs in lasers with spatial hole burning, dispersion and Kerr
Nikola Opačak, Benedikt Schwarz
Frequency modulated (FM) frequency combs constitute an exciting alternative to generate equidistant spectra. The full set of Maxwell-Bloch equations is reduced to a single master e…
Semiconductor ring laser frequency combs induced by phase turbulence
Marco Piccardo, Benedikt Schwarz, Dmitry Kazakov +10
Semiconductor ring lasers are miniaturized devices that operate on clockwise and counterclockwise modes. These modes are not coupled in the absence of intracavity reflectors, which…
Graphene photodetector integrated on a photonic crystal defect waveguide
Simone Schuler, Daniel Schall, Daniel Neumaier +4
We present a graphene photodetector for telecom applications based on a silicon photonic crystal defect waveguide. The photonic structure is used to confine the propagating light i…
Laser radio transmitter
Marco Piccardo, Michele Tamagnone, Benedikt Schwarz +8
Since the days of Hertz, radio transmitters have evolved from rudimentary circuits emitting around 50 MHz to modern ubiquitous Wi-Fi devices operating at gigahertz radio bands. As…
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…
Single-mode instability in standing-wave lasers: The quantum cascade laser as a self-pumped parametric oscillator
Tobias S. Mansuripur, Camille Vernet, Paul Chevalier +13
We report the observation of a clear single-mode instability threshold in continuous-wave Fabry-Perot quantum cascade lasers (QCLs). The instability is characterized by the appeara…
