Monolithic Integration of Mid-Infrared Quantum Cascade Lasers and Frequency Combs with Passive Waveguides
Ruijun Wang, Philipp Täschler, Zhixin Wang +3
Mid-infrared semiconductor lasers in photonic integrated circuits are of considerable interest for a variety of industrial, environmental, and medical applications. However, photon…
Mid-infrared quantum cascade laser frequency combs with a microstrip-like line waveguide geometry
Filippos Kapsalidis, Barbara Schneider, Matthew Singleton +4
In this work, a design for a mid-infrared quantum cascade laser (QCL) frequency comb source that enhances the high frequency response and the comb characteristics of the device is…
Gigahertz Self-referenceable Frequency Comb from a Semiconductor Disk Laser
Christian A. Zaugg, Alexander Klenner, Mario Mangold +8
We present a 1.75-GHz self-referenceable frequency comb from a vertical external-cavity surface-emitting laser (VECSEL) passively modelocked with a semiconductor saturable absorber…
Two-dimensional imaging of the spin-orbit effective magnetic field
L. Meier, G. Salis, E. Gini +2
We report on spatially resolved measurements of the spin-orbit effective magnetic field in a GaAs/InGaAs quantum-well. Biased gate electrodes lead to an electric-field distribution…
Measurement of Rashba and Dresselhaus spin-orbit magnetic fields
Lorenz Meier, Gian Salis, Ivan Shorubalko +3
Spin-orbit coupling is a manifestation of special relativity. In the reference frame of a moving electron, electric fields transform into magnetic fields, which interact with the e…
Optimized stray-field-induced enhancement of the electron spin precession by buried Fe gates
L. Meier, G. Salis, N. Moll +5
The magnetic stray field from Fe gates is used to modify the spin precession frequency of InGaAs/GaAs quantum-well electrons in an external magnetic field. By using an etching proc…
