Characterization of Long-Term Stable Photonic Microwaves based on a Difference Frequency Comb
S. Mueller, T. Puppe
We report on a novel method for optical microwave generation using a frequency comb based on difference-frequency generation, which passively eliminates the carrier-envelope offset…
Spectral dynamics in broadband frequency combs with overlapping harmonics
Weichen Fan, Furkan Ayhan, Thibault Wildi +8
Optical frequency combs and their spectra of evenly spaced discrete laser lines are essential to modern time and frequency metrology. Recent advances in integrated photonic wavegui…
Chip-integrated extended-cavity mode-locked laser in the visible
Lisa V. Winkler, Govert Neijts, Hubertus J. M. Bastiaens +9
Mode-locked lasers are of interest for applications such as biological imaging, non-linear frequency conversion, and single-photon generation. In the infrared, chip-integrated mode…
Widely-tunable and narrow-linewidth hybrid-integrated diode laser at 637 nm
Lisa V. Winkler, Kirsten Gerritsma, Albert van Rees +7
We present hybrid-integrated extended cavity diode lasers tunable around 637 nm, with a gain-wide spectral coverage of 8 nm. This tuning range allows addressing the zero-phonon lin…
Wide-range resistivity characterization of semiconductors with terahertz time-domain spectroscopy
Joshua Hennig, Jens Klier, Stefan Duran +9
Resistivity is one of the most important characteristics in the semiconductor industry. The most common way to measure resistivity is the four-point probe method, which requires ph…
Hybrid integrated near UV lasers using the deep-UV Al2O3 platform
C. A. A. Franken, W. A. P. M. Hendriks, L. V. Winkler +9
Hybrid integrated diode lasers have so far been realized using silicon, polymer, and silicon nitride (Si3N4) waveguide platforms for extending on-chip tunable light engines from th…
