Endless frequency shifting of optical frequency comb lines
Optics Express, 2013 The functional principle of a novel technique for frequency shifting lines of an optical frequency comb is demonstrated. The underlying principle is to shift the carrier frequency by changing the carrier phase within the time span between subsequent pulses of a mode-locked laser used as comb generator.

Coherent control of mid-infrared frequency comb by optical injection of near-infrared light
APL Photonics, 2023 We demonstrate the use of a low power near-infrared laser illuminating the front facet of a quantum cascade laser (QCL) as an optical actuator for the coherent control of a mid-infrared frequency comb. We show that with appropriate current control of the
