Ultrabroadband femtosecond two-dimensional ultraviolet transient absorption

Majed Chergui, Frank van Mourik, Cristina Consani

We present a broadband two-dimensional transient absorption setup for the UV around 300 nm with a time resolution of 150 fs. A narrowband, frequency tunable pump pulse and a broadband probe pulse are generated from the output of a noncollinear optical para ...

Optical injection locking of polarization modes and spatial modes in single-aperture VCSELs and VCSEL arrays emitting at 1.3 mu m

Elyahou Kapon, Grigore Suruceanu, Alexandru Mereuta, Vladimir Iakovlev, Alexei Sirbu, Andrei Caliman, Elodie Lamothe, Christopher Michael Long

We report the injection locking of specific spatial modes and polarization modes of 1.3 mu m wavelength vertical surface emitting lasers (VCSELs) in single-aperture devices and phase-coupled arrays. The optical injection is realized using a master laser (M ...

Universal formation dynamics and noise of Kerr-frequency combs in microresonators

Tobias Kippenberg, Tobias Herr, Emanuel Gavartin

Optical frequency combs allow for the precise measurement of optical frequencies and are used in a growing number of applications. The new class of Kerr-frequency comb sources, based on parametric frequency conversion in optical microresonators, can comple ...

Cost-effective thermally-managed 1.55-μm VECSEL with hybrid mirror on copper substrate

Elyahou Kapon, Alexandru Mereuta, Alexei Sirbu

An electroplated copper substrate was evaluated for heat dissipation in 1.55-μm optically pumped vertical extended cavity surface emitting lasers (OP-VECSELs). It is a cost-effective and flexible solution compared with the previously proposed chemical vapo ...

Bipolar pulse coding for enhanced performance in Brillouin distributed optical fiber sensors

Luc Thévenaz, Marcelo Alfonso Soto Hernandez

We propose and experimentally demonstrate the possibility to use a pump signal based on bipolar pulse sequences using single-sideband suppressed-carrier (SSB-SC) modulation in Brillouin optical time-domain analysis (BOTDA) sensors. The SSB-SC modulated pum ...

Dual-pump push-pull polarization control using stimulated Brillouin scattering

Luc Thévenaz, Sang Hoon Chin, Nikolay Primerov

Stimulated Brillouin scattering (SBS) amplification of probe signals is highly polarization dependent. Maximum and minimum gain values are associated with a pair of orthogonal states of polarization (SOP), which are related to the pump SOP. Since the maxim ...

Polarization pulling based on stimulated Brillouin scattering in a dual-pump configuration

Luc Thévenaz, Sang Hoon Chin, Nikolay Primerov

Stimulated Brillouin scattering (SBS) amplification of probe signals is highly polarization dependent. Maximum and minimum gain values are associated with a pair of orthogonal states of polarization (SOP) at the fiber output. Since the maximum gain is much ...

Inhibition of the Emission of Electromagnetic Modes of Photonic Crystal Cavities with a Top Mirror

Romuald Houdré, Nicolas Le Thomas

By imaging the angular spectrum of optical modes confined within subwavelength volumes, we investigate the impact of metallic and dielectric surrounding layers on the optical emission properties of planar silicon photonic crystal cavity. By scanning a mirr ...
