Complete compensation of pulse broadening in an amplifier-based slow light system using a nonlinear regeneration element

We experimentally demonstrate complete compensation of pulse broadening in an amplifier-based slow light system. The configuration of the delay line basically consists of two stages: a conventional Brillouin slow light system and a nonlinear regeneration e ...

Linear micromirror array for broadband femtosecond pulse shaping in phase and amplitude

Nico de Rooij, Jonathan Leon Wolf

We are developing a linear array of micromirrors designed for optical, femtosecond laser pulse shaping. It is a bulkmicromachined device, capable of retarding or diminishing certain laser frequencies in order to perform phase and amplitude modulation withi ...

Time-domain distributed sensor with 1 cm spatial resolution based on Brillouin dynamic gratings

Luc Thévenaz, Sang Hoon Chin, Nikolay Primerov, Kwang-Yong Song

We propose and experimentally demonstrate the highest-resolution BOTDA system ever reported using Brillouin dynamic grating in a polarization-maintaining fiber (PMF). Acoustic waves containing the information of local Brillouin frequency are generated by a ...

A multi-color fast-switching microfluidic droplet dye laser

Demetri Psaltis

We describe a multi-color microfluidic dye laser operating in whispering gallery mode based on a train of alternating droplets containing solutions of different dyes; this laser is capable of switching the wavelength of its emission between 580 nm and 680 ...

Terahertz Quantum Cascade Lasers based on two-dimensional photonic crystal resonators

Romuald Houdré, Marcella Giovannini, Jérôme Faist, Lorenzo Sirigu

We demonstrate high spectral control from surface emitting THz Quantum Cascade Lasers based on a two-dimensional photonic crystal cavity. The perforated top metallic contact acts as an in plane resonator in a tight double-metal plasmonic waveguide providin ...

Large linear micromirror array for UV femtosecond laser pulse shaping

Nico de Rooij, Jonathan Leon Wolf

We are fabricating a bulk-micromachined micromirror device for laser pulse shaping applications on femtosecond time scales. An array of micromirrors is used to individually retard or diminish certain laser frequencies spanning from the UV to the near-infra ...

Near-field mapping of quantum dot emission from single-photonic crystal cavity modes

Romuald Houdré, Laurent Balet, Nicolas Le Thomas, Massimo Gurioli

We directly investigate, by means of near-field spectroscopy, the spatial distribution of the optical cavity modes of 2D photonic crystal microcavities. Numerical simulations confirm that the photoluminescence maps of quantum dots embedded in the photonic ...

Terahertz photonic crystal quantum cascade lasers

Romuald Houdré, Hua Zhang, Jérôme Faist

We combine photonic crystal and quantum cascade band engineering to create an in-plane laser at terahertz frequency. We demonstrate that such photonic crystal lasers strongly improve the performances of terahertz quantum cascade material in terms of thresh ...

Optical parametric generation in periodically poled KTiOP O4 via extended phase matching

Demetri Psaltis, Ye Pu

We report an experimental demonstration of optical parametric generation in a periodically poled KTiOP O4 crystal based on the principle of mirrorless optical parametric oscillation. A femtosecond pump pulse spectrally centered at 792 nm from a Ti:sapphire ...
