Application of optical single-sideband laser in Raman atom interferometry [PDF]

, 2018
A frequency doubled I/Q modulator based optical single-sideband (OSSB) laser system is demonstrated for atomic physics research, specifically for atom interferometry where the presence of additional sidebands causes parasitic transitions. The performance

Broadband Optical Serrodyne Frequency Shifting

, 2009
We demonstrate serrodyne frequency shifting of light from 200 MHz to 1.2 GHz with an efficiency of better than 60 percent. The frequency shift is imparted by an electro-optic phase modulator driven by a high-frequency, high-fidelity sawtooth waveform ...

Widely tunable laser frequency offset lock with 30 GHz range and 5 THz offset [PDF]

, 2013
We demonstrate a simple and versatile method to greatly extend the tuning range of optical frequency shifting devices, such as acousto-optic modulators (AOMs).

An integrated processor for photonic quantum states using a broadband light-matter interface

, 2014
Faithful storage and coherent manipulation of quantum optical pulses are key for long distance quantum communications and quantum computing. Combining these functions in a light-matter interface that can be integrated on-chip with other photonic quantum ...

Zeptosecond‐Scale Single‐Photon Gyroscope

Advanced Quantum Technologies, Volume 7, Issue 9, September 2024.
A novel approach coupling Sagnac interferometry with estimation theory is proposed, presenting a fully fibre‐based sensor that employs a quadrupole winding‐fibre optic gyroscope together with serrodyne modulation and nanowire detectors to achieve an unparalleled photon delay detection limit of 26 zeptoseconds.

Single-channel laser Doppler vibrometers integrated on silicon-on-insulator (SOI) [PDF]

, 2012
Multi-location velocity measurements of a vibrating surface are of interest recently. By scanning the laser beam of a single-point laser Doppler vibrometer (LDV) across the surface of interest, one can realize the multi-location vibration measurement ...

Space-Time Medium Functions as a Perfect Antenna-Mixer-Amplifier Transceiver

, 2020
We show that a space-time-varying medium can function as a front-end transceiver, i.e., an antenna-mixer-amplifier. Such a unique functionality is endowed by space-time surface waves associated with complex space-time wave vectors in a subluminal space ...
