Thresholdless Lasing of Nitride Nanobeam Cavities on Silicon

Nicolas Grandjean, Jean-François Carlin, Raphaël Butté, Ian Michael Rousseau, Noelia Vico Triviño, Gordon Jens Callsen

We present a temperature dependent optical and quantum-optical characterization of close-to-ideal lasing in GaN-based nanobeam cavities. Measuring the photon statistics of emission allows us to prove high-beta lasing at room temperature, and thresholdless ...

Characterization and modeling of microstructured chalcogenide fibers for efficient mid-infrared wavelength conversion

Camille Sophie Brès, Davide Grassani, Svyatoslav Kharitonov, Adrien Billat, Sida Xing

We experimentally demonstrate wavelength conversion in the 2 μm region by four-wave mixing in an AsSe and a GeAsSe chalcogenide photonic crystal fibers. A maximum conversion efficiency of −25.4 dB is measured for 112 mW of coupled continuous wave pump in a ...

Bringing short-lived dissipative Kerr soliton states in microresonators into a steady state

Tobias Kippenberg, Victor Brasch, Michael Wolfgang Geiselmann, Martin Hubert Peter Pfeiffer

Dissipative Kerr solitons have recently been generated in optical microresonators, enabling ultrashort optical pulses at microwave repetition rates, that constitute coherent and numerically predictable Kerr frequency combs. However, the seeding and excitat ...

Intense THz source based on BNA organic crystal pumped at Ti:sapphire wavelength

Christoph Peter Hauri, Mostafa Shalaby

We report on high-energy terahertz pulses by optical rectification (OR) in the organic crystal N-benzyl-2-methyl-4-nitroaniline (BNA) directly pumped by a conventional Ti:sapphire amplifier. The simple scheme provides an optical-to-terahertz conversion eff ...

Quantum state resolved molecular beam reflectivity measurements: CH4 dissociation on Pt(111)

Rainer Beck, Ana Gutiérrez González, Helen Jane Chadwick

The King and Wells molecular beam reflectivity method has been used for a quantum state resolved study of the dissociative chemisorption of CH4 on Pt(111) at several surface temperatures. Initial sticking coefficients were measured for incident CH4 prepare ...

IR-induced conformational isomerization of a helical peptide in a cold ion trap

Thomas Rizzo, Aleksandra Zabuga, Annette Svendsen, Caroline Seaiby

In this work we use laser-induced population transfer techniques to study the conformational isomerization of a helical peptide, Ac-Phe-(Ala)5-LysH+, in a cold ion trap. In one scheme, called IR-UV hole-filling spectroscopy, a single conformation is select ...

Harmonization of chaos into a soliton in Kerr frequency combs

Tobias Kippenberg

Dissipative Kerr solitons have paved the way to broadband and fully coherent optical frequency combs in microresonators. Here, we demonstrate numerically that slow frequency tuning of the pump laser in conjunction with phase or amplitude modulation corresp ...

Novel scanning method for distortion-free BOTDA measurements

Luc Thévenaz, Marcelo Alfonso Soto Hernandez, Zhisheng Yang, Alejandro Dominguez Lopez

Systematic errors induced by distortions in the pump pulse of conventional Brillouin distributed fiber sensors are thoroughly investigated. Experimental results, supported by a theoretical analysis, demonstrate that the two probe sidebands in standard Bril ...
