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…
