Nanomechanical optical fiber with embedded electrodes actuated by joule heating

open access: yes, 2014
Nanomechanical optical fibers with metal electrodes embedded in the jacket were fabricated by a multi-material co-draw technique. At the center of the fibers, two glass cores suspended by thin membranes and surrounded by air form a directional coupler ...

Tailoring optical fibers for cell transfection [PDF]

open access: yes, 2012
Optical transfection is a promising technique for the delivery of foreign genetic material into cells by transiently changing the permeability of the cell membrane.

Optical Gas Sensor Fabrication Based on Porphyrin-Anchored Electrostatic Self-Assembly onto Tapered Optical Fibers [PDF]

open access: yes, 2012
Tapered optical fibers with nano-assembled coatings of thicknesses of order tens of nanometres were used for the detection of ammonia gas. The film coating was composed of alternate layers of tetrakis-(4-sulfophenyl) porphine (TSPP) and poly(allylamine ...

Dual Temperature and Strain Measurement with the Combined Fluorescence Lifetime and Bragg Wavelength Shift Approach in Doped Optical Fiber [PDF]

open access: yes
We have constructed fiber-optic sensors to measure temperature and strain by combining the properties of fiber Bragg gratings with the fluorescent lifetimes of various doped fibers.

Fabrication of multiple parallel suspended-core optical fibers by sheet-stacking [PDF]

open access: yes, 2014
We demonstrate the fabrication of a novel type of optical fibers with multiple parallel air-suspended cores by the sheet-stacking method. Using this technique we have constructed optical fibers with up to 10 parallel micron-size suspended cores. No extra

Optical router for optical fiber sensor networks based on a liquid crystal cell [PDF]

open access: yes, 2003
Optical fiber sensor networks are evolving rapidly. They are used because of the inert nature of optical fibers allowing no electromagnetic interference and safe applications in inflammable atmospheres; other relevant characteristics are their low ...

Fiber-optic chemical sensing with Langmuir-Blodgett overlay waveguides [PDF]

open access: yes, 1999
Fiber-optic chemical sensing has been demonstrated with a side-polished single- mode optical fiber, evanescently coupled to chemically sensitive Langmuir- Blodgett (LB) overlay waveguides.

Performance Analysis of a Noncontact Plastic Fiber Optical Fiber Displacement Sensor with Compensation of Target Reflectivity [PDF]

open access: yes, 2013
An inexpensive fiber-based noncontact distance sensor specific for monitoring short-range displacements in micromachining applications is presented. To keep the overall costs low, the sensor uses plastic optical fibers and an intensiometric approach ...

Optical network architectures for dynamic reconfiguration of full duplex, multiwavelength, radio over fiber [PDF]

open access: yes, 2006
In recent years there have been rapid advances in the techniques to generate and transport radio signals over optical fiber, but very little has been done to date to develop the concept of a full duplex, multiwavelength, radio-over-fiber network ...

All-optical modulation and demultiplexing systems with significant timing jitter tolerance through incorporation of pulse-shaping fiber Bragg gratings [PDF]

open access: yes, 2002
In this letter, we demonstrate the use of a superstructured fiber Bragg grating to preshape optical pulses to obtain optimal operation of nonlinear all-optical switches.
