Acquisition of multiple phase derivatives from a single frame in digital holographic interferometry

Pramod Rastogi, Rishikesh Dilip Kulkarni

This paper proposes a technique to extract two-dimensional multiple phase derivatives (strains, slopes, and shearing strains) from a single frame of the interference fringe pattern recorded in an optical setup with multiple illumination beams. In the propo ...

Generation of 1.5-octave intense infrared pulses by nonlinear interactions in DAST crystal

Christoph Peter Hauri

Infrared pulses with large spectral width extending from 1.2 to 3.4 μm are generated in the organic crystal DAST (4-N, N-dimethylamino-4′-N′-methylstilbazolium tosylate). The input pulse has a central wavelength of 1.5 μm and 65 fs duration. With 2.8 mJ in ...

Set-up for broadband Fourier-transform multidimensional electronic spectroscopy

Majed Chergui, Frank van Mourik, Christopher Alexander Arrell, Andre Al Haddad, José Javier Pancracio Ojeda Andara, Adrien Alexis Paul Chauvet

We present a compact passively phase-stabilized ultra-broadband 2D Fourier transform setup. A gas (argon)-filled hollow core fiber pumped by an amplified Ti:Al2O3 laser is used as a light source providing spectral range spanning from 420 to 900 nm. Sub-10- ...

Kerr nonlinearity of Thulium-doped fiber near 2 um

Camille Sophie Brès, Svyatoslav Kharitonov, Adrien Billat, Steevy Joyce Cordette, Ludovic Zulliger

The nonlinear coefficient and group velocity dispersion of a thulium-doped fiber near 2μm are evaluated via four-wave mixing. Nonlinearity of thulium-doped fiber can be used for the design of doped-fiber lasers in this spectral region. ...

Dephasing effects on coherent exciton-polaritons and the breakdown of the strong coupling regime

Benoît Marie Joseph Deveaud, Daniel Oberli, Marcia Portella Oberli, Stéphane Trebaol, Mitchell David Anderson, Naotomo Takemura, Souvik Biswas

Using femtosecond pump-probe spectroscopy, we identify excitation-induced dephasing as a major mechanism responsible for the breakdown of the strong coupling between excitons and photons in a semiconductor microcavity. The effects of dephasing are observed ...

Wave dispersion in periodic post-buckled structures

Alessandro Spadoni, Florian Paul Robert Maurin

Wave propagation in pinned-supported, post-buckled beams can be described with the Korteweg de Vries (KdV) equation. Finite-element simulations however show that the KdV is applicable only to post-buckled beams with strong pre-compression. For weak and mod ...

Effect of Dispersion Fluctuations on Longitudinal Gain Evolution in Phase-Sensitive Parametric Amplifiers

Luc Thévenaz, Camille Sophie Brès, Marcelo Alfonso Soto Hernandez, Fatemeh Alishahi, Mohammad Amin Shoaie, Andrey Denisov

A Brillouin probing method is proposed to extract the distribution of signal power along phase-sensitive parametric amplifiers. Operation near the zero-dispersion-wavelength shows enhanced sensitivity to dispersion fluctuations, allowing effective extracti ...

Study of spatial dispersion in graphene parallel-plate waveguides and equivalent circuit

Julien Perruisseau-Carrier, Juan Sebastian Gomez Diaz

We propose an equivalent longitudinal circuit to characterize surface plasmon polaritons (SPPs) propagation along spatially dispersive graphene parallel plate waveguides. This circuit allows the fast analysis of the propagating modes, taking into account t ...
