The optical frequency comb fibre spectrometer
Nature Communications, 2016 AbstractOptical frequency comb sources provide thousands of precise and accurate optical lines in a single device enabling the broadband and high-speed detection required in many applications. A main challenge is to parallelize the detection over the widest possible band while bringing the resolution to the single comb-line level.

Microresonator frequency comb optical clock
Optica, 2014 Optical-frequency combs enable measurement precision at the 20th digit, and accuracy entirely commensurate with their reference oscillator. A new direction in experiments is the creation of ultracompact frequency combs by way of nonlinear parametric optics in microresonators.

Precision frequency transfer with fiber frequency combs
Frontiers in Physics, 2022 We review methods for precision transfer of frequencies across broad optical wavelength ranges. Single-branch supercontinuum generation allows for a frequency transfer stability of < 1 × 10−17 in 1 s across an octave.

Latest advances in optical frequency combs based on quadratic non‐linearity
IET Optoelectronics, 2020 Second‐order non‐linear susceptibility (χ2) is the cause of many non‐linear processes in optics including second harmonic generation, sum frequency generation and difference frequency generation. Optical frequency combs based on χ2, i.e.

Advanced Materials Technologies, EarlyView.Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Optical Lattice Trap for Kerr Solitons
, 2017 We show theoretically and numerically that dichromatic pumping of a nonlinear microresonator by two continuous wave coherent optical pumps creates an optical lattice trap that results in the localization of intra-cavity Kerr solitons with soliton ...
