Electro-optic frequency shift of single photons from a quantum dot [PDF]
NanophotonicsQuantum dots (QDs) are a promising source of single photons mainly due to their on-demand operation. However, their emission wavelength depends on their size and immediate surroundings in the solid-state environment. By applying a serrodyne electro-optic

Single-modulator, direct frequency comb spectroscopy via serrodyne modulation. [PDF]
Opt Lett, 2023 Traditional electro-optic frequency comb spectrometers rely upon the use of an acousto-optic modulator (AOM) to provide a differential frequency shift between probe and local oscillator (LO) legs of the interferometer. Here we show that these modulators can be replaced by an electro-optic phase modulator (EOM) which is driven by a ...

Robust laser frequency stabilization by serrodyne modulation [PDF]
Optics Letters, 2012 We report the relative frequency stabilization of a distributed feedback erbium-doped fiber laser on an optical cavity by serrodyne frequency shifting. A correction bandwidth of 2.3 MHz and a dynamic range of 220 MHz are achieved, which leads to a strong

Optical nonreciprocity via transmissive time-modulated metasurfaces. [PDF]
Nanophotonics, 2022 Abstract The frequency mixing property of time‐modulated metasurfaces, attributed to the well‐known phenomenon of temporal photonic transition, has led to several exotic functionalities in the last lustrum. Based on this concept, we demonstrate the possibility of achieving nonreciprocal responses in the near‐infrared regime via combining a time ...
