Integrated optical frequency combs

2017 19th International Conference on Transparent Optical Networks (ICTON), 2017
Optical frequency combs (OFCs) are a revolutionary light source for numerous applications due to their precisely spaced coherent optical wavelengths. his paper will focus on OFCs for employment in next generation dense/ultra-dense wavelength division multiplexed high-speed optical communication systems, which places stringent requirements on the OFC ...

Squeezed optical frequency combs in a microresonator

Frontiers in Optics + Laser Science 2021, 2021
We report a demonstration of optical microresonator-based frequency comb (microcomb) in the deterministic quantum regime, where 20 pairs of two-mode squeezed comb mode pairs are generated in a silica microresonator on a silicon chip.

Mapping of the Optical Frequency Comb to the Atom Velocity Comb

15th International Conference on Ultrafast Phenomena, 2006
We present the experimental and theoretical study of the resonant excitation of rubidium atoms with fs pulse train in the conditions when the pulse repetition period is shorter than the atomic relaxation time. The velocity selective optical pumping of the ground state hyperfine levels and velocity comb-like excited state hyperfine level populations are

Accuracy of optical frequency comb generation in optical fiber

Optics Letters, 1999
We evaluated the accuracy of an optical frequency comb in optical fibers by measuring the frequency shift after a sideband from an electro-optic modulator had passed through the fiber. We found that a frequency drift of a few hertz was due largely to a variation in the ambient temperature that corresponded to an increase in the square root of the Allan

Characterization of the Frequency Stability of a Multibranch Optical Frequency Comb

IEEE Transactions on Instrumentation and Measurement, 2020
Presently, ultra-precise optical clocks’ comparisons can be performed easily using the optical frequency combs (OFCs) as a transfer oscillator. In this scheme, different OFC branches are usually used to enable optical clocks’ comparison at different wavelengths.

Optical frequency comb at NIM

Digest of the LEOS Summer Topical Meetings, 2005., 2005
Absolute measurement of stabilized lasers' optical frequency is an important subject in metrology. The traditional tool for establishing the llnk between Cs atomic frequency standard and an optical frequency is harmonic frequency chain ['I. But, such a harmonic frequency chain is very expensive to built and complicated to operate.

Properties of optical frequency combs

ILSC 2009: Proceedings of the International Laser Safety Conference, 2009
Optical frequency combs have attracted much interest over the last 10 years. They have applications in optical frequency metrology, optical atomic clocks, waveform synthesis and high field studies. Frequency combs have a very broad optical spectrum. The spectral breadth is essential for determining the comb offset frequency, which is a key quantity for
