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

Martinus Gijs, Daniel Migliozzi, Bingying Zhao

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 ...

Leveraging wafer-level manufacturing process limitations to increase large scale fused silica microlens array uniformity

Toralf Scharf, Wilfried Noell, Raoul Kirner, Jeremy Béguelin

The wafer-level production of Fused Silica microlens arrays is limited by systematic process non-uniformities. The common molten resist-reflow process with subsequent dry-etching allows for manufacturing of microlens arrays on 200 mm wafers. A thorough pro ...

Multi-material micro-electromechanical fibers with bendable functional domains

Fabien Sorin, Wei Yan, Alexis Gérald Page, Yunpeng Qu, Marco Volpi

The integration of increasingly complex functionalities within thermally drawn multi-material fibers is heralding a novel path towards advanced soft electronics and smart fabrics. Fibers capable of electronic, optoelectronic, piezoelectric or energy harves ...

Demonstration of distributed shape sensing based on Brillouin scattering in multi-core fibers

Luc Thévenaz, Marcelo Alfonso Soto Hernandez, Zhiyong Zhao

In this paper we demonstrate distributed shape sensing based on stimulated Brillouin scattering in a multi-core fiber (MCF). Brillouin optical time-domain analysis with differential pulse-width pairs is implemented to measure the local tangential strain-in ...

Observation device with optical compensation

Philippe Renaud, Yann Barrandon, David Vincent Bonzon, David Forchelet, Steve Béguin

The invention concerns an observation device such as cell culture wells comprising an optical element such as a lens or a filter, or even combinations thereof, for compensating an optical effect induced on a sample contained in the observation device and i ...

Distributed shape sensing using Brillouin scattering in multi-core fibers

Luc Thévenaz, Marcelo Alfonso Soto Hernandez, Zhiyong Zhao

A theoretical and experimental study on the response of Brillouin scattering in multi-core optical fibers (MCF) under different curving conditions is presented. Results demonstrate that the Brillouin frequency shift of the off-center cores in MCF is highly ...

Landmark Detection for Fusion of Fundus and MRI Toward a Patient-Specific Multimodal Eye Model

Meritxell Bach Cuadra, Carlos Ciller

Ophthalmologists typically acquire different image modalities to diagnose eye pathologies. They comprise, e.g., Fundus photography, optical coherence tomography, computed tomography, and magnetic resonance imaging (MRI). Yet, these images are often complem ...

Upconversion Particle as a Local Luminescent Brownian Probe: A Photonic Force Microscopy Study

László Forró, Andrzej Sienkiewicz, Flavio Maurizio Mor, Sylvia Jeney

Near-infrared (NIR) light sensitive lanthanide-doped NaYF4 upconversion particles (UCPs) are gaining increasing attention as local probes in biomedical applications. Here, we implemented a photonic force microscope (PFM) to manipulate and study the optical ...
