Thermally stable access to microresonator solitons via slow pump modulation

Tobias Kippenberg, Victor Brasch, Junqiu Liu, Tobias Herr

Temporal dissipative Kerr solitons (DKSs) in microresonators provide ultra-short optical pulses and low-noise frequency combs with gigahertz to terahertz repetition rates. Owing to their unique properties, they have found application in fields, including o ...

Probing charge transfer processes at p-GaAs electrodes under weak optical excitation

Jean-Philippe Ansermet, Christophe Roussel, Felix Blumenschein, Mika Antero Tamski

The p-GaAs photocathode/acetonitrile interface was characterised in the dark and with tens of mu W/cm(2) laser powers at 830 nm wavelength, using cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). Two redox mediators were used that p ...

Multiplexing Soliton-Combs in Optical Microresonators

Tobias Kippenberg, Maxim Karpov, Erwan Guillaume Albert Lucas, Arslan Sajid Raja

Nonlinear wave mixing in optical microresonators new perospects for compact optical frequency combs with many promising applications. We demonstrate simultaneous generation of multiple frequency combs from a single optical microresonator and a single conti ...

Cooling dynamics of electrons in MAPbBr(3) probed in the deep-UV

Majed Chergui, Thomas Charles Henry Rossi, Malte Oppermann, Peter Chen, Lijie Wang, Yu-Hsien Chiang

Transient absorption in the Visible and in the deep-UV is performed on MAPbBr(3) thin films with 3.1 eV pump excitation. The UV probe can access higher order transitions in the material exploring different high-symmetry points of the Brillouin zone. Uncorr ...

Flip-Chip Wafer-Fused OP-VECSELs Emitting 3.65 W at the 1.55-mu m Waveband

Elyahou Kapon, Alok Rudra, Grigore Suruceanu, Alexandru Mereuta, Andrei Caliman, Pascal Gallo

Optically pumped vertical external cavity surface emitting lasers (VECSELs) based on flip-chip gain mirrors emitting at the 1.55 mu m wavelength range are reported. The gain mirrors employ wafer-fused InAlGaAs/InP quantum well heterostructures and GaAs/AlA ...

A microphotonic astrocomb

Tobias Kippenberg, Michael Wolfgang Geiselmann, Junqiu Liu, Tobias Herr, Miles Henry Anderson, Stefan Kundermann

Earth-like planets, dark energy and variability of fundamental physical constants can be discovered by observing wavelength shifts in the optical spectra of astronomical objects(1-5). These wavelength shifts are so tiny that exquisitely accurate and precis ...

Energy and orientation independence of the channel branching in Ne* + ND3 chemi-ionisation

Andreas Osterwalder, Sean Dennis Steven Gordon

Collisions of excited neon atoms with ammonia molecules can lead to two reaction processes, dissociative ionisation and Penning ionisation. Both processes result in the ionisation of the ammonia molecule and redistribution of the electronic energy into the ...
