We demonstrate the use of dual-comb spectroscopy for isotope ratio measurements. We show that the analysis spectral range of a free-running near-infrared dual-comb spectrometer can be extended to the midinfrared by difference frequency generation to

We provide the experimental proof of concept of on-chip 90° corner waveguide arrays based on ultra-long-range surface plasmon polariton waveguides working in TM-polarization at 1.55 μm. The single-mode waveguides comprise a thin gold-photoresist co

Background: Electrically controlled optical metal antennas are an emerging class of nanodevices enabling a bilateral transduction between electrons and photons. At the heart of the device is a tunnel junction that may either emit light upon injection

We report on the experimental generation of an octave-spanning supercontinuum in a 2.2 cm-long titanium dioxide optical waveguide with two zero dispersion wavelengths. The resulting on-chip supercontinuum reaches the visible wavelength range as well

We numerically study the underlying nonlinear dynamics of ultra-broadband optical wavelength converters based on fourth-order scalar modulation instability. Specifically, we demonstrate the spontaneous emergence of solitons and trapped radiation wave

We demonstrate the transmission of a 10-Gbit/s optical data signal in the 2 µm waveband into titanium dioxide waveguides. Error-free transmissions have been experimentally achieved taking advantage of a 23-dB insertion loss fiber-to-fiber grating-ba

We present an electro-optic dual-comb spectrometer operating in the mid- infrared for carbon dioxide sensing. Isotopic ratio measurements of 13CO2/12CO2 are per- formed and the results show good agreements with the expectations.
