In traditional interferometric measurements, a physical quantity that changes the phase of a resonator is monitored through a change of its transmission. Interferometry inside a laser exploits the ultimate Q‐factor of that resonator, and converts the phase to be measured into a frequency. A mode‐locked laser with two intracavity pulses emits two frequency combs of the same repetition rate. The quantity to be measured (a sub‐nano displacement, a nonlinear index, an acceleration or rotation, a magnetic or electric field) produces a minute phase change (≥10−10 rad) in one of the two intracavity pulses, which is converted into a frequency, measured by beating the two pulse trains emitted by the laser. This paper presents methods of operating mode‐locked lasers in which two independent pulses circulate, producing two frequency combs of the same repetition rate. Various examples of physical quantities that can be measured through this technique are presented.

“…Frequency tunable microwave signal generators have been proposed and demonstrated based on a number of techniques, including optical injection locking, optical phase-lock loop, and dual-wavelength lasers [1]. The dual-wavelength-laser approach relies on the implementation of a single-longitudinal-mode laser that emits an output at two wavelengths with identical or orthogonal polarizations [2][3][4][5][6][7][8][9][10][11][12]. The microwave signal can be generated as a result of the beating between the two wavelengths.…”

“…Dual-polarization fiber grating lasers have been fabricated to implement a tunable microwave source [8][9][10][11][12]. The laser emits outputs along the two orthogonal polarizations and the beat frequency is tuned by transversely compressing the laser cavity to change the intracavity birefringence.…”

Implementation of a widely tunable microwave signal generator based on dual-polarization fiber grating laser

et al. 2015

In this paper, we demonstrate the implementation of a widely tunable microwave signal generator based on a dual-polarization fiber grating laser. The laser contains two strong, wavelength-matched Bragg gratings photoinscribed in an Er-doped fiber and emits two polarization modes when pumped with a 980 nm laser diode. By beating the two modes, a microwave signal with a signal-to-noise ratio over 60 dB can be obtained. For a free running laser the fluctuations in intensity and frequency of the microwave signal are ±1 dB and ±5 kHz, respectively, and the noise level is about -40 dBc/Hz at 1 kHz. The frequency can be continuously tuned from 1.8 to 15.1 GHz, by transversely loading the laser cavity and changing the intracavity birefringence by use of a piezoelectric transducer-based mechanical device. The measured response time rate of tuning is about 90 MHz/μs and the intensity fluctuation at different frequencies is less than ±1.5 dB. The frequency fluctuation under loading is controlled within 1 MHz by introducing an electrical feedback.
