Femtosecond-laser direct-write photoconductive patterns on tellurite glass
Yves Bellouard, Gözden Torun, Anastasia Romashkina
We report the formation of arbitrary photoconductive patterns made of tellurium (Te) nanocrystals by exposing a tellurite (TeO2-based) glass to femtosecond laser pulses. During this process, Te/TeO2-glass nanocomposite interfaces with photoconductive prope ...
2024Terahertz waveform synthesis in integrated thin-film lithium niobate platform
Ileana-Cristina Benea-Chelmus, Jérôme Faist, Francesca Fabiana Settembrini
Bridging the "terahertz gap" relies upon synthesizing arbitrary waveforms in the terahertz domain enabling applications that require both narrow band sources for sensing and few-cycle drives for classical and quantum objects. However, realization of custom ...
Berlin2023On the interaction of femtosecond laser pulses with layered dielectric materials
Materials properties are strictly dependent on their microstructure. The internal symmetries and the disposition of the constituting atoms of a material, which depend on its crystallographic structure, greatly affect its response to mechanical, electromagn ...
EPFL2023Linear and nonlinear applications of miniaturized silicon nitride microresonators
Photonic integrated circuits (PICs) are the subject of massive interest due to the range of applications they can provide at a huge scale while building on well-established CMOS technologies. One of the critical parameters defining a technology's maturity ...
EPFL2023Broadband Air-Coupled Ultrasound Emitter and Receiver Enable Simultaneous Measurement of Thickness and Speed of Sound in Solids
Air-coupled ultrasound sensors have advantages over contact ultrasound sensors when a sample should not become contaminated or influenced by the couplant or the measurement has to be a fast and automated inline process. Thereby, air-coupled transducers mus ...
MDPI2023A tunable femtosecond fiber laser source for multiphoton emission microscopy
Pierre-Marc Jean Marie Dansette
Second harmonic generation microscopy is used to image interfaces or non-centrosymmetric structures and molecules. Two-photon fluorescence microscopy can image molecules within cells without using markers. Thus those technics have lead to advances in our u ...
EPFL2021Direct time-of-flight SPAD image sensors for light detection and ranging
Depth sensing is an increasingly important feature in many applications of consumer, automotive, augmented/virtual reality (AR-VR), space and bio-medical imaging. Long range, high depth resolution, high spatial resolution, and high frame rates are often co ...
EPFL2021Self-Injection Locking of a Gain-Switched Laser Diode
We experimentally observe a self-injection locking regime of the gain-switched laser to a high-Q optical microresonator. We reveal that the comb generated by the gain-switched laser experiences a dramatic reduction of comb-teeth linewidths in this regime. ...
AMER PHYSICAL SOC2021Fundamentals and perspectives of ultrafast photoferroic recording
The ability to switch ferroics (ferro-, ferri-, antiferromagnets, ferroelectrics, multiferroics) between two stable bit states is one of the keystones of modern data storage technology. Due to many new ideas, originating from fundamental research during th ...
2020Generating optical pulses via a soliton state of an optical microresonator coupled with a chip based semiconductor laser
Tobias Kippenberg, Hairun Guo, Arslan Sajid Raja
A light pulse source (100), being adapted for generating repetitive optical pulses (1), comprises a continuous wave cw laser device (10) being arranged for providing cw laser light (2), an optical waveguide (20) being optically coupled with the cw laser de ...
