Precise RF Phase Measurement by Optical Sideband Generation Using Mach–Zehnder Modulators
نویسندگان
چکیده
A novel radio frequency (RF) phase measurement method that uses optical modulation was proposed. The mathematical model of Mach–Zehnder modulator (MZM) characterization reviewed. By measuring the output sideband power modulator, difference electric signals fed to experimentally measured, and picosecond-level accuracies were achieved. This technique is expected be useful for radio-over-fiber-based antenna array systems.

Precise characterization of 6Li Feshbach resonances using trap-sideband-resolved RF spectroscopy of weakly bound molecules.
We perform radio-frequency dissociation spectroscopy of weakly bound 6Li2 Feshbach molecules using low-density samples of about 30 molecules in an optical dipole trap. Combined with a high magnetic field stability, this allows us to resolve the discrete trap levels in the radio-frequency dissociation spectra. This novel technique allows the binding energy of Feshbach molecules to be determined ...
متن کاملStatus of Precise RF Power Measurement
Radio frequency (RF) power is one of the most important quantity in RF metrology. In recent years significant progress has been achieved in developing new primary RF power standards with extended frequency ranges and improved uncertainties. These developments and the results of numerous international comparisons in the field of precise RF power measurements carried out in the last years are rev...
متن کاملMeasurement of nonlinear optical coefficients by phase-matched harmonic generation
A wide range of nonlinear optical coefficients and various systems of notation have been used to describe optical second-harmonic generation (5MG). To avoid possible confusion, the techniques of optical nonlinear coefficient measurement and the elementary theory of SHG are briefly reviewed. Absolute and relative nonlinear coefficient measurements by phase-matched SHG are described. The followin...
متن کاملPhase-coherent orthogonally polarized optical single sideband modulation with arbitrarily tunable optical carrier-to-sideband ratio.
We propose and experimentally verify a novel approach to achieve phase-coherence orthogonally polarized optical single sideband (OSSB) modulation with a tunable optically carrier-to-sideband ratio (OCSR). In our scheme, the orthogonally polarized OSSB signal is achieved using a dual-polarization quadrature phase shift keying (DP-QPSK) modulator without an optical band-pass filter (OBPF). Theref...
متن کاملDouble and single side-band suppressed-carrier optical modulator implemented at 1320 nm using LiNbO3 crystals and bulk optics
We perform double sideband and single sideband suppressed-carrier modulators using a MachZehnder interferometer in free space. Two bulk LiNbO3 crystals are used to modulate the optical beam at 1319 nm in both branches of the interferometer. We present experimental results of the optical spectrum using heterodyne measurement technique. These results show maximum carrier and sideband suppression ...
