We demonstrate a simple scheme which uses only an intensity modulator and an OSA to achieve low-power (∼100nW, 10aJ/pulse at 10GHz), self-referenced, amplitude and phase characterization of high repetition rate optical frequency comb sources.
We demonstrate fast characterization ( ~ 1.4 ??s) of both the dispersion and dispersion slope of long optical fiber links ( ~ 25 km) using dual quadrature spectral interferometry with an optical frequency comb. Compared to previous spectral interferometry experiments limited to fiber lengths of meters, the long coherence length and the periodic delay properties of frequency combs, coupled with fast...
A self-referenced technique for measuring the phase of individual optical frequency comb lines is demonstrated. Spectral frequency shear is obtained from sum frequency generation of a signal comb with wavelength separated reference tones.
We demonstrate fast (~1.4 mus) spectral amplitude and phase characterization of optical arbitrary waveforms generated by line-by-line shaping of a 10 GHz frequency comb. Our technique enables coherent spectral phase measurement after dispersive propagation over long (~50 km) lengths of optical fiber.
We present a novel technique for electric field cross-correlation using two frequency combs. This technique is for characterization of optical arbitrary waveforms and allows independent control of phase and group delay without a mechanical stage.
Optical combs and high-resolution optical filtering are utilized for high-fidelity measurements of photodiode harmonic distortion. This new technique uses a single laser and phase modulation-alleviating requirements on laser frequency stabilization and modulator bias control.
We demonstrate single measurement retrieval of amplitude and phase of wide temporal window (100 ps) optical waveforms from a 10 GHz optical frequency comb source and a line-by-line pulse shaper by using dual-quadrature spectral interferometry.
A new self-referenced technique for measuring the amplitude and phase of individual optical frequency comb lines is demonstrated. Spectral frequency shear is obtained from sum frequency generation of a signal comb with wavelength separated reference tones.
Ultraweak, ~300-fs pulses at 1.5 μm are measured by second-harmonic generation intensity autocorrelation and frequency-resolved optical gating using aperiodically poled LiNbO3 waveguides. Our reference-free scheme can retrieve complex fields with 120-aJ coupled pulse energy, corresponding to a sensitivity of 2 x 10-6 mW, ~5 orders of magnitude better than the previous record
A wavelength-parallel polarimeter has been developed for measuring both spectral states-of-polarization and spectral degrees-of-polarization of over 100 (scalable up to thousands) wavelengths in parallel within 1 millisecond.
