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…
Picosecond pulses from a mid-infrared interband cascade laser
Johannes Hillbrand, Maximilian Beiser, Aaron Maxwell Andrews +6
The generation of mid-infrared pulses in monolithic and electrically pumped devices is of great interest for mobile spectroscopic instruments. The gain dynamics of interband cascad…
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…
