Optical frequency comb photoacoustic spectroscopy
Ibrahim Sadiek, Tommi Mikkonen, Markku Vainio +2
We report the first photoacoustic detection scheme using an optical frequency comb - the optical frequency comb photoacoustic spectroscopy (OFC-PAS). OFC-PAS combines the broad spe…
Less is more - enhancement of second-harmonic generation from metasurfaces by reduced nanoparticle density
Robert Czaplicki, Antti Kiviniemi, Mikko J. Huttunen +7
We investigate optical second-harmonic generation (SHG) from metasurfaces where noncentrosymmetric V-shaped gold nanoparticles are ordered into regular array configurations. In con…
Demonstration of Optical Nonlinearity in InGaAsP/InP Passive Waveguides
Shayan Saeidi, Payman Rasekh, Kashif M. Awan +3
We report on the study of the third-order nonlinear optical interactions in InGaAsP/InP strip-loaded waveguides. The material composition and waveguide…
Diode-laser-pumped continuous-wave mid-infrared optical parametric oscillator
Ville Ulvila, Markku Vainio
We report a singly resonant continuous-wave optical parametric oscillator (SRO), which is pumped by a semiconductor laser system and operates in the mid-infrared region (2.9 to 3.6…
Using surface lattice resonances to engineer nonlinear optical processes in metal nanoparticle arrays
Mikko J. Huttunen, Payman Rasekh, Robert W. Boyd +1
Collective responses of localized surface plasmon resonances, known as surface lattice resonances (SLRs) in metal nanoparticle arrays, can lead to high quality factors (~100), larg…
Towards optical frequency comb generation in continuous-wave pumped titanium indiffused lithium niobate waveguide resonators
Michael Stefszky, Ville Ulvila, Zeina Abdallah +2
Much progress, both experimentally and theoretically, has recently been made towards optical frequency comb generation from continuously pumped second-order nonlinear systems. Here…
Enhancement of bulk second-harmonic generation from silicon nitride films by material composition
K. Koskinen, R. Czaplicki, A. Slablab +8
We present a comprehensive tensorial characterization of second-harmonic generation from silicon nitride films with varying composition. The samples were fabricated using plasma-en…
Nonlinear continuous-wave optical propagation in nematic liquid crystals: interplay between reorientational and thermal effects
Alessandro Alberucci, Urszula A. Laudyn, Armando Piccardi +4
Thanks to their unique properties, nematic liquid crystals feature a variety of mechanisms for light-matter interactions. For continuous-wave optical excitations, the two dominant…
Breather solitons in highly nonlocal media
Alessandro Alberucci, Chandroth P. Jisha, Gaetano Assanto
We investigate the breathing of optical spatial solitons in highly nonlocal media. Generalizing the Ehrenfest theorem, we demonstrate that oscillations in beam width obey a fourth-…
Guiding light via geometric phases
Sergei Slussarenko, Alessandro Alberucci, Chandroth P. Jisha +4
Known methods for transverse confinement and guidance of light can be grouped into a few basic mechanisms, the most common being metallic reflection, total internal reflection and…
Atomic layer deposited second order nonlinear optical metamaterial for back-end integration with CMOS-compatible nanophotonic circuitry
StÉphane Clemmen, Artur Hermans, Eduardo Solano +6
We report the fabrication of artificial unidimensional crystals exhibiting an effective bulk second-order nonlinearity. The crystals are created by cycling atomic layer deposition…
Optical Rogue Waves in Whispering-Gallery-Mode Resonators
Aurélien Coillet, John Dudley, Goery Genty +2
We report a theoretical study showing that rogue waves can emerge in whispering gallery mode resonators as the result of the chaotic interplay between Kerr nonlinearity and anomalo…
Real time noise and wavelength correlations in octave-spanning supercontinuum generation
T. Godin, B. Wetzel, T. Sylvestre +8
We use dispersive Fourier transformation to measure shot-to-shot spectral instabilities in femtosecond supercontinuum generation. We study both the onset phase of supercontinuum ge…
On the statistical interpretation of optical rogue waves
Miro Erkintalo, Goëry Genty, John M. Dudley
Numerical simulations are used to discuss various aspects of "optical rogue wave" statistics observed in noise-driven fiber supercontinuum generation associated with highly incoher…
