Integrated Source of Spectrally Filtered Correlated Photons for Large-Scale Quantum Photonic Systems

Matteo Galli, Christophe Marcel Georges Galland, Davide Grassani

We demonstrate the generation of quantum-correlated photon pairs combined with the spectral filtering of the pump field by more than 95 dB on a single silicon chip using electrically tunable ring resonators and passive Bragg reflectors. Moreover, we perfor ...

Generation and application of dynamic gratings in optical fibers using stimulated Brillouin scattering

Luc Thévenaz, Nikolay Primerov

Since the invention of optical fiber cable data transmission using light has become ubiquitous in the past years. Nonlinear optical effects, which are hardly noticed in our daily life, have become crucial and highly influential for the design and performan ...

Dual-mode temperature compensation technique for laser stabilization to a crystalline whispering gallery mode resonator

Tobias Kippenberg, Albert Schliesser

Frequency stabilization of a diode laser locked to a whispering gallery mode (WGM) reference resonator made of a MgF2 single crystal is demonstrated. The strong thermal dependence of the difference frequency between two orthogonally polarized TE an TM mode ...

Design and fabrication technology for high performance electrical pumped terahertz photonic crystal band edge lasers with complete photonic band gap

Romuald Houdré, Jérôme Faist, Hua Zhang

We detail the design and fabrication technology of two-dimensional photonic crystal (PhC) band edge emitting quantum cascade lasers (QCLs) operating at terahertz frequencies (similar to 3.3 THz). The entire QCL active layer has been deeply etched to form a ...

Large vacuum Rabi splitting in a multiple quantum well GaN-based microcavity in the strong-coupling regime

Jean-François Carlin, Pierre Stadelmann, Nicolas Grandjean, Raphaël Butté, Eric Feltin, Gabriel Christmann, Antonino Francesco Castiglia, Anas Mouti

An AlInN/AlGaN microcavity (MC) containing a GaN/Al0.2Ga0.8N multiple quantum well (MQW) structure is investigated through room temperature (RT) photoluminescence and reflectivity experiments. A vacuum Rabi splitting as large as 50 meV at RT is reported fo ...

Crack-free highly reflective AlInN/AlGaN bragg mirrors for UV applications

Jean-François Carlin, Marc Ilegems, Julien Dorsaz, Nicolas Grandjean, Raphaël Butté, Eric Feltin, Gabriel Christmann

We report the growth of highly reflective distributed Bragg reflectors (DBRs) in the UV region using the Al0.85In0.15N/Al0.2Ga0.8N lattice-matched system. The DBRs were deposited on nearly strain-free Al0.2Ga0.8N templates to avoid strain-induced structura ...
