High efficiency THz generation in DSTMS, DAST and OH1 pumped by Cr:forsterite laser

We investigated Terahertz generation in organic crystals DSTMS, DAST and OH1 directly pumped by a Cr:forsterite laser at central wavelength of 1.25 mu m. This pump laser technology provides a laser-to-THz energy conversion efficiency higher than 3 percent. ...

Miniature silicon Michelson interferometer characterization for dimensional metrology

Maurine Malak Karam Awadallah

Dimensional metrology applications require performing measurements of profile and form/shape of parts at a nanometer-level of accuracy. Therefore, the metrological characteristics of a miniature optical micro-probe based on a Michelson interferometer are e ...

Optical Injection and Lasing Dynamics in Long-Wavelength VCSELs With Intracavity Patterning

Elyahou Kapon, Benjamin Dwir, Alexandru Mereuta, Vladimir Iakovlev, Alexei Sirbu, Andrei Caliman, Zlatko Mickovic, Dalila Ellafi, Christopher Michael Long

We present the static and optical injection response of wafer-fused long-wavelength VCSELs with and without intracavity patterning. It is found that the extra optical cavity patterning increases the gain anisotropy between orthogonal polarization modes, in ...

Temporal broadening of attosecond photoelectron wavepackets from solid surfaces

Christopher Alexander Arrell

The response of solids to electromagnetic fields is of crucial importance in many areas of science and technology. Many fundamental questions remain to be answered about the dynamics of the photoexcited electrons that underpin this response, which can evol ...

Intense, carrier frequency and bandwidth tunable quasi single-cycle pulses from an organic emitter covering the Terahertz frequency gap

Christoph Peter Hauri

In Terahertz (THz) science, one of the long-standing challenges has been the formation of spectrally dense, single-cycle pulses with tunable duration and spectrum across the frequency range of 0.1–15 THz (THz gap). This frequency band, lying between the el ...

TiO2 membrane high-contrast grating reflectors for vertical-cavity light-emitters in the visible wavelength regime

Georg Rossbach, Ehsan Hashemi

In this work, the authors describe a novel route to achieve a high reflectivity, wide bandwidth feedback mirror for GaN-based vertical-cavity light emitters; using air-suspended high contrast gratings in TiO2, with SiO2 as a sacrificial layer. The TiO2 fil ...

Stability of Fiber Bragg Gratings Fabricated Using UV Ar+ and ArF Excimer in Bismuth-Aluminum-co-Doped Silica Fibers

Hans Georg Limberger, Georgios Violakis

Continuous annealing of fiber Bragg gratings fabricated using cw and pulsed laser irradiation in Bi-Al-co-doped fibers of different concentrations show activation energy spectra linked to Bi-Al. Thermal stability maps were obtained by their analytical repr ...

A microfluidic flow-cell for the study of the ultrafast dynamics of biological systems

Majed Chergui, Adrien Alexis Paul Chauvet

The study of biochemical dynamics by ultrafast spectroscopic methods is often restricted by the limited amount of liquid sample available, while the high repetition rate of light sources can induce photodamage. In order to overcome these limitations, we de ...

Widely Tunable Picosecond-Pulsed Source near 2 μm based on Cascaded Raman Wavelength Shifting

Camille Sophie Brès, Adrien Billat, Steevy Joyce Cordette, Yu-Pei Tseng

We demonstrate a cavity-less picosecond pulsed source near 2μm, tunable over more than 200nm based on third order cascaded Raman wavelength shifting. Up to 44% conversion is achieved for 100mW peak powers at 200MHz repetition rate. ...
