Effect of Cavity Lifetime Variation on the Static and Dynamic Properties of 1.3-μm Wafer-Fused VCSELs

Elyahou Kapon, Alexandru Mereuta, Vladimir Iakovlev, Alexei Sirbu, Andrei Caliman, Zlatko Mickovic, Dalila Ellafi

We investigate experimentally the impact of photon cavity lifetime variations on the static and dynamic performance of high-speed 1.3-mu m wavelength wafer-fused vertical-cavity surface-emitting lasers (VCSELs). The photon lifetime is modified by decreasin ...

200 km fiber-loop Brillouin distributed fiber sensor using bipolar Golay codes and a three-tone probe

Luc Thévenaz, Marcelo Alfonso Soto Hernandez, Zhisheng Yang

Aiming at taking full advantage of bipolar codes, a method using a three-tone probe is proposed to alleviate the probe power limitation imposed by pump depletion in Golay-coded Brillouin distributed fiber sensors. Experimental results validate the techniqu ...

Bond-Selective and Mode-Specific Dissociation of CH3D and CH2D2 on Pt(111)

Rainer Beck, Hirokazu Ueta, Phil Morten Hundt, Maarten Eduard van Reijzen

Infrared laser excitation of partially deuterated methanes (CH3D and CH2D2) in a molecular beam is used to control their dissociative chemisorption on a Pt(111) single crystal and to determine the quantum state-resolved dissociation probabilities. The excl ...

Performance limit of two-pump Brillouin fiber sensors obtained by Manakov modulation instability

Luc Thévenaz, Marcelo Alfonso Soto Hernandez, Mohammad Mehdi Alem Karladani, Javier Urricelqui Polvorinos

The Manakov modulation instability is shown to determine the performance limit of long-distance Brillouin fiber sensors utilizing orthogonally-polarized pumps. Numerical simulations of the Manakov equation are supported by the experimental measurement of a ...

Analytical model and experimental verification of the critical power for modulation instability in optical fibers

Luc Thévenaz, Marcelo Alfonso Soto Hernandez, Mohammad Mehdi Alem Karladani

Modulation instability is thoroughly investigated and a simple analytical model for its power critically modifying the wave properties in terms of system parameters is derived and experimentally validated. The differences on the modulation instability gain ...

Photonic chip-based optical frequency comb using soliton Cherenkov radiation

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

Optical solitons are propagating pulses of light that retain their shape because nonlinearity and dispersion balance each other. In the presence of higher-order dispersion, optical solitons can emit dispersive waves via the process of soliton Cherenkov rad ...

Back-Contacted Silicon Heterojunction Solar Cells: Optical-Loss Analysis and Mitigation

Christophe Ballif, Antoine Descoeudres, Bertrand Yves Paul Paviet-Salomon, Matthieu Despeisse, Stefaan De Wolf, Sylvain Nicolay, Loris Barraud, Andrea Tomasi

We analyze the optical losses that occur in interdigitated back-contacted amorphous/crystalline silicon heterojunction solar cells. We show that in our devices, the main loss mechanisms are similar to those of two-side contacted heterojunction solar cells. ...

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 ...
