Planar micromachined glass cantilevers utilising integrated Bragg Fabry-Perot cavities

, 2010
Here we demonstrate a glass cantilever based on a unique micromachining and etching approach, combined with UV written Bragg gratings. We shall also discuss the increase in sensitivity by using two Bragg gratings to form Fabry-Pérot cavity.

Cavity‐Compatible Light Extraction in Top‐Emitting Microcavity OLEDs via a Gentle Internal Corrugation Layer and Resonance‐Matched Narrowband Emission

Advanced Science, EarlyView.
A gentle internal corrugation layer conformally reshapes the microcavity OLED stack, redistributing confined optical power toward extractable channels while preserving cavity‐controlled emission. Combined with optical clear resin and a resonance‐matched narrowband pTSF emissive system, this cavity‐compatible architecture delivers an external quantum ...

Mode‐Resolved Phonon Dynamics Under Chemical Pressure in SnTe Thermoelectrics

Advanced Science, EarlyView.
Chemical pressure reshapes low‐energy optical phonons in SnTe, altering their dispersion and scattering with heat‐carrying acoustic modes. Positive and negative pressure states modify phonon frequencies and lifetimes in distinct ways, revealing how mode‐selective lattice perturbations regulate acoustic–optical interactions and suppress lattice thermal ...

Energy scaling properties of Laguerre-Gauss modes in gas-filled multipass cells [PDF]

EPJ Web of Conferences
We present energy scaling from 50 μJ up to 150 μJ of a gas-filled multipass cell (MPC) nonlinear compression setup with a Gaussian and an LG03 beam, compressed to 60 fs.

Design of nanofibres for efficient stimulated Raman scattering in the evanescent field [PDF]

Journal of the European Optical Society-Rapid Publications, 2013
Nanofibres can be produced with diameters smaller than the wavelength of the light they guide. In this regime, the guided mode presents a strong evanescent field well adapted to the excitation of “evanescent nonlinearities”.

SGLT2 Inhibitors and Cardiovascular Outcomes in Patients With Fabry Disease: Observations From a Federated Research Network. [PDF]

Diabetes Obes Metab
ABSTRACT Background and Aim Fabry disease (FD) is frequently complicated by renal impairment and cardiovascular events; however, evidence on sodium–glucose cotransporter‐2 inhibitors (SGLT2i) in this population is scarce. Accordingly, we assessed the association between SGLT2i exposure and cardiovascular outcomes in adults with FD. Methods We conducted

Prevalence of Anderson-Fabry disease in male patients with late onset hypertrophic cardiomyopathy [PDF]

, 2002
Background-Although studies have suggested that "late-onset" hypertrophic cardiomyopathy (HCM) may be caused by sarcomeric protein gene mutations, the cause of HCM in the majority of patients is unknown.

Low Threshold Vertical Cavity Surface Emitting Lasers Based on CsPbI3 Thin Films

Advanced Science, EarlyView.
The first vertical‐cavity surface‐emitting laser (VCSEL) based on CsPbI3 thin films is fabricated by planar hot pressing. By optimizing the cavity design through optical gain assessment and rigorous coupled‐wave analysis, the VCSEL achieved an exceptionally low lasing threshold of 2.8 µJ cm−2.
