A micromachined thermo-optical light modulator based on semiconductor-to-metal phase transition
In this research, a micromachined thermo-optical light modulator was realized based on the semiconductor-to-metal phase transition of vanadium dioxide (VO_2) thin film. VO_2 undergoes a reversible phase transition at approximately 68 0C, which is accompanied with drastic changes in its electrical …

Mechanisms and Implementation of Thermo-Optical Annealing in Silica Fiber Sensors for Radiation-Induced Attenuation Mitigation
… magnets, temperature sensors based on optical fibers provide an effective solution for rapid, distributed measurement, with low sensitivity to electromagnetic interference. At the cryogenic temperatures and high radiation doses associated with this application, however, optical fibers …

On the theory of the optical stretcher : optics, mechanics, and thermal effects
The optical stretcher (OS) is dual-beam laser trap capable of capturing and deforming micron-sized particles or biological cells. It can be employed to measure cell-mechanical properties and, thus, to monitor physiological changes, such as differentiation, and to diagnose diseases that affect the …

Seasonal Pattern and Sources of Particulate Carbon in Kananaskis and Calgary, Alberta
… in Kananaskis and Calgary were assessed using thermo-optical methods. Vehicle exhaust was inferred to be dominant source of carbon throughout the year with an identical OC/EC of 22±14 in Calgary and 22±5 in Kananaskis in dry deposition. Biogenic OC signal was absent in Kananaskis in …

Material Related Effects on the Structural Thermal Optical Performance of a Thermally Tunable Narrowband Interferometric Spectral Filter
… is a backscatter lidar technique that employs an optical/spectral filter to distinguish between particulate (Mie) and molecular (Rayleigh) backscattered light. By separating the two types of returns, higher accuracy measurements are possible that will enable improved climate models, air quality …

Integrated optical phased arrays for lidar applications
It is no wonder that research in Si photonics (optical components embedded on a silicon platform) has bloomed so rapidly the last few years. Combining low loss, strong refractive index contrast (and, thus, light confinement), with electro-optical and thermo-optical effects, allows for the …

Thermal characterisation of miniature hotplates used in gas sensing technology
… were studied, using both IR and a novel thermo-incandescence microscopy. The IR emitters were fabricated using complementary-metal-oxide semiconductor (CMOS) based processing technology and consisted of a miniature micro-heater, fabricated using tungsten metallisation. There is a …

Sintering kinetics and properties of highly pure lead zirconate titanate ceramics
… The sintering behavior was monitored in a thermo-optical dilatometer and a kinetic-field approach was employed to obtain the activation energy for sintering of PZT ceramics with different compositions. The bulk ceramics were characterized in terms of microstructure, dielectric, …
