We present a theoretical analysis into the fundamental physical mechanisms contributing to backscattering in hollow-core antiresonant fibers. We consider Rayleigh scattering originating from the hollow regions of the fiber, which may be filled with g

Detector non-linearity is an important factor limiting the maximal power and hence the signal-to-noise ratio (SNR) in dual-comb interferometry. To increase the SNR without overwhelming averaging time, photodetector non-linearity must be properly hand

Laser sources operating in the 2 µm spectral region play an important role for sensing and spectroscopy, and potentially for optical communication systems. In this work, we demonstrate a widely tunable hybrid silicon-fiber laser operating in the 2

We characterized the frequency noise of a tunable Raman laser using the passive coherent discriminator technique. We estimated the relative laser linewidth and experimentally observed the conversion of pump relative intensity noise to the Raman laser

Photodetector nonlinearity, the main limiting factor in terms of optical power in the detection chain, is corrected to improve the signal-to-noise ratio of a short-time measurement in dual-comb spectroscopy. An iterative correction algorithm minimizi

Short pulse lasers are used to characterize the nonlinear response of amplified photodetectors. Two widely used balanced detectors are characterized in terms of amplitude, area, broadening, and balancing the mismatch of their impulse response. The dy

Self-sufficient correction algorithms have recently been developed to estimate and compensate the relative frequency noise between two free-running frequency combs using only their dual-comb interferograms (IGMs). However, such algorithms are limited

The elastic backscattering of light in optical fiber is a fundamental phenomenon that sets the ultimate performance of several fiber systems such as gyroscopes and bidirectional transfer links. Until now, efforts to reduce the backscattering coeffici

We show that optical fibers doped with as little as 7 mole% P 2 O 5 have 27% lower temperature sensitivity of accumulated phase (relevant in interferometry) as compared to standard optical fibers. We believe full temperature insensitivity can be reac

We report methane spectroscopy with dual electro-optic combs using optical hybrids and pseudo-random modulation. This system helps investigate sources of systematic errors in dual-comb spectroscopy.
