, 1997 A twin-bridge calorimeter using optical fiber as the sensor element was constructed and tested. This system demonstrates the principle and capability of using optical fibers for heat-flow measurements of special nuclear material. This calorimeter uses piezoelectric-generated phase-carrier modulation with subsequent electronic signal processes to allow ...

Advanced Biology, EarlyView.This study investigates the photosensitizing potential of Passiflora cincinnata in Antimicrobial Photodynamic Therapy (aPDT) against skin infection caused by Methicillin‐resistant Staphylococcus aureus (MRSA) in a senescent murine model. The P. cincinnata exhibits antimicrobial activity, with reduced bacterial load, lower leukocyte infiltration, and ...

Low loss QKD optical scheme for fast polarization encoding
, 2017 We present a new optical scheme for BB84 protocol quantum key distribution (QKD). The proposed setup consists of a compact all-fiber polarization encoding optical scheme based on LiNbO3 phase modulators, single laser source and two single-photon ...

Efficient fiber-optical interface for nanophotonic devices [PDF]
, 2014 We demonstrate a method for efficient coupling of guided light from a single mode optical fiber to nanophotonic devices. Our approach makes use of single-sided conical tapered optical fibers that are evanescently coupled over the last ~10 um to a ...

Parity-time symmetry in wavelength space within a single spatial resonator
Nature Communications, 2020 Most conventional PT-symmetric systems contain two physically separated modes. Here the authors proposed a PT-symmetric microwave optoelectronic oscillator, where the gain and loss modes are confined in a single spatial resonator, resulting in an ...

Optics Express, 2008 Described herein are initial experimental details and properties of a silicon core, silica glass-clad optical fiber fabricated using conventional optical fiber draw methods. Such semiconductor core fibers have potential to greatly influence the fields of nonlinear fiber optics, infrared and THz power delivery.

The FEBS Journal, 2007 Optical‐fiber bundles have been employed as a versatile substrate for the fabrication of high‐density microwell arrays. In this minireview, we discuss the application of optical‐fiber‐bundle arrays for a variety of biological problems. For genomics studies and microbial pathogen detection, individual beads have been functionalized with DNA probes and ...
