Shaped Laser Pulses for Microsecond Time-Resolved Cryo-EM: Outrunning Crystallization during Flash Melting

Marcel Drabbels, Constantin Richard Krüger, Nathan Junior Mowry

Water vitrifies if cooled at rates above 3 × 105 K/s. In contrast, when the resulting amorphous ice is flash heated, crystallization occurs even at a more than 10 times higher heating rate, as we have recently shown. This may present an issue for microseco ...

Light-Driven Thermo-Optical Effects in Nanoresonator Arrays

Giulia Tagliabue, Alfredo Angelo Luigi Naef, Ershad Mohammadi, Theodoros Tsoulos

Thermonanophotonics, that is the study of photothermal effects in optical nanoantennas, has recently attracted growing interest. In particular, going beyond thermoplasmonic designs, thermo-optical modulation of dielectric nanoantennas opens new opportuniti ...

Single-frequency violet and blue laser emission from AlGaInN photonic integrated circuit chips

Tobias Kippenberg, Anat Siddharth

Chip-based, single-frequency and low phase-noise integrated photonic laser diodes emitting in the violet (412 nm) and blue (461 nm) regime are demonstrated. The GaN-based edge-emitting laser diodes were coupled to high-quality on-chip micro-resonators for ...

Defect formation and mitigation during laser powder bed fusion of copper

Carl Tore Viktor Lindström

Additive manufacturing (AM) is a group of processing technologies which has the potential to revolutionize manufacturing by allowing easy manufacturing of complex shapes and small series. One AM-method which is of high interest for processing of metals is ...

Semiconductor laser chip stabilization by Si3N4 microresonator and Kerr comb generation

Tobias Kippenberg, Andrey Voloshin, Mirjam Pfeiffer

The experimental study of the InPlaser diode stabilization by high-Q Si3N4 microresonator is presented. We demonstrate how this stabilized laser diode considered as a pump laser may be used for optical frequency comb generation in the same microresonator. ...

Continuous Wave Blue Lasing in III-Nitride Nanobeam Cavity on Silicon

Nicolas Grandjean, Jean-François Carlin, Raphaël Butté, Noelia Vico Triviño

IIIV photonics on silicon is an active and promising research area. Here, we demonstrate room-temperature (RT) lasing in short-wavelength III-nitride photonic crystal nanobeam cavities grown on silicon featuring a single InGaN quantum well (QW). In the low ...
