Recirculating frequency-shifting loop for flexible optical chirp generation and FMCW LiDAR
Alexander Mrokon, Sebastian Schöler, Leonard Vossgrag +2
A recirculating frequency-shifting loop (FSL) provides a highly flexible platform for generating coherent optically chirped light with tunable bandwidth, duration, chirp rate and r…

Influence of mechanical resonances on the linearity of adiabatic frequency conversion in whispering gallery resonators
Alexander Mrokon, Till Wachweger, Dongsung Shin +2
Adiabatic frequency conversion enables fast and efficient tuning of laser light by coupling it into an optical resonator whose eigenfrequency is varied on a timescale shorter than…

Electrically-induced resonance shifts of whispering gallery resonators made of barium magnesium fluoride
Alexander Mrokon, Heike Kraft, Dongsung Shin +4
Barium magnesium fluoride (BMF) is a ferroelectric crystal with a transparency range far beyond the one of other optical materials. In particular, its low loss in the deep ultravio…
