Post-tensioning of glass beams: Analytical determination of the allowable pre-load

Alain Nussbaumer, Pieter Christian Louter, Jagoda Cupac

The effectiveness of post-tensioning in enhancing the fracture resistance of glass beams depends on the level of compressive pre-stress introduced at the glass edge surface that will in service be exposed to tensile stresses induced by bending. Maximum pre ...

Phase calibration of a basic bright-field microscope for 3D metrology of transparent samples at the nanoscale

Martinus Adela Maria Gijs, Daniel Migliozzi

Optical retrieval of the structure of transparent objects at the nano-scale requires adapted methods capable of probing their interaction with suitable light. Scattering events, for instance, depend on the content and the arrangement of the medium encounte ...

Investigation of femtosecond laser-tuned thermomechanical properties of fused silica

Pieter Vlugter

The thermomechanical properties of materials are among the most important properties for designing precision instruments, in particular for devices seeking high-dimensional stability, invariant temperature-elastic properties or low thermoelastic losses. De ...

Topological optomechanically induced transparency

Romain Christophe Rémy Fleury, Farzad Zangeneh Nejad

The interaction of optical and mechanical degrees of freedom can lead to several interesting effects. A prominent example is the phenomenon of optomechanically induced transparency (OMIT), in which mechanical movements induce a narrow transparency window i ...

Dual-frequency-comb spectrometer and spectroscopy method for spectroscopic investigation of a sample

Tobias Kippenberg, Junqiu Liu, Hairun Guo, Wenle Weng

A dual-frequency-comb spectrometer and a method for spectroscopic investigation of a sample are described. The spectrometer includes first and second frequency comb devices for emitting laser pulses along first and second light paths, wherein the repetitio ...

Monolithic perovskite/silicon-heterojunction tandem solar cells processed at low temperature

Michael Graetzel, Mohammad Khaja Nazeeruddin, Ulf Anders Hagfeldt, Michael Saliba, Antonio Abate, Juan-Pablo Correa-Baena, Ludmilla Steier

Tandem solar cells combining silicon and perovskite absorbers have the potential to outperform state-of-the-art high efficiency silicon single junction devices. However, the practical fabrication of monolithic silicon/perovskite tandem solar cells is chall ...

Advanced Diamond Microfabrication for Microoptics and Photonics

Marcell Kristof Kiss

Diamond is an exceptional material - hard, stiff, transparent, which makes it ideal for the fabrication of optical and mechanical systems that take advantage of these properties. Diamond is not only "better", but it offers the possibility of integrating br ...

A Learned Shape-Adaptive Subsurface Scattering Model

Wenzel Alban Jakob, Delio Aleardo Vicini

Subsurface scattering, in which light refracts into a translucent material to interact with its interior, is the dominant mode of light transport in many types of organic materials. Accounting for this phenomenon is thus crucial for visual realism, but exp ...
