Tailoring Risken-Nummedal-Graham-Haken instability in quantum cascade lasers
(2017-06)The multimode Risken-Nummedal-Graham-Haken (RNGH) instability in a CW laser arises due to Rabi splitting of the lasing transition induced by the lasing mode. Observation of large spectral broadening on the order of 2? Rabi ... -
Tapered monolithic mode-locked laser diode with 200pJ pulse energy for space applications
(2019-03-01)European Space Agency (ESA) considers Mode-Locked Semi-Conductor Lasers as a promising technology for precision metrology systems in space such as High Accuracy Absolute Long Distance Measurement. We report our progress ... -
Tapered Monolithic Mode-Locked Laser Diode with 200pJ Pulse Energy for Space Applications
(2018-09)To the best of our knowledge, we demonstrate the first mode-locked semiconductor laser reaching 201pJ picosecond pulses without amplifier at low repetition frequency of 2.89GHz, with a very-long (13.5mm) multi-sections ... -
Technologien für energieautarke Anwendungen
(2016)Das Internet of Things (IoT) wird oft als die Zukunftshoffnung für neue industrielle Wertschöpfung und Innovation dargestellt. Dies trifft speziell für energieautarke IoT-Produkte zu. Das CSEM bietet hier Hand. -
Temporal dissipative solitons in a fabry-pérot microresonator driven by optical pulses
(2017)A nonlinear optical microresonator is driven by picosecond laser pulses resulting in formation of temporal dissipative solitons. These femtosecond solitons are stable and generated at a fraction of the power required in ... -
Temporal solitons in microresonators driven by optical pulses
(2017-08-21)<p>By driving a high-<i>Q</i> fibre-based Fabry–Pérot microresonator with periodic, picosecond optical pulses, deterministic generation of stable femtosecond dissipative cavity solitons has been experimentally realized.</p> -
The amazing improvement of silicon heterojunction technology: ready for a true mass market launch
(2018)Silicon heterojunction solar cells have less manufacturing steps and have allowed achieving higher efficiency than PERC cells. However the market has been slow in taking up the technology. Here we discuss some of the ... -
The Greenpower house: From simulation to reality
(2013-06)The Greenpower concept addresses the steadily increasing electric consumption by optimizing the energy fluxes in a modern house. The latter can be equipped with photovoltaic panels, an electrolyzer system (hydrogen generator ... -
The Handbook of Cuffless Blood Pressure Monitoring: A Practical Guide for Clinicians, Researchers, and Engineers
(2019)This book is the first comprehensive overview of the emerging field of cuffless blood pressure monitoring. Increasing clinical evidence proves that longitudinal measurements of blood pressure allow for earlier detection ... -
The impact of silicon solar cell architecture and cell interconnection on energy yield in hot and sunny climates
(2017)Extensive knowledge of the dependence of solar cell and module performance on temperature and irradiance is essential for their optimal application in the field. Here we study such dependencies in the most common high-efficiency ... -
The integrated swiss miniature atomic clock
(2013-07)The detailed design of the Swiss Miniature Atomic Clock (Swiss-MAC) was presented by CSEM in 2012. This paper describes the progress made in the meantime towards the realization of the integrated Swiss-MAC, by presenting ...
