At the end of the 1970s, it was confirmed that dielectric multilayers can sustain Bloch surface waves (BSWs). However, BSWs were not widely studied until more recently. Taking advantage of their high-quality factor, sensing applications have focused on BSW ...
Optical frequency references are devices providing well-defined and stable optical frequency responses to incoming radiation for applications such as high-precision spectroscopy and optical fibre communications. To stabilise the emission frequency of laser ...
The present invention relates to a device including a ferroic material having a ferroelectric order parameter and including at least two domains, as well as a first and second electrode in electrical contact with the ferroic material. The device is configu ...
In this thesis, we present the development of a tunable Multi-Heterodyne Scanning Near-Field Optical Microscope (MH-SNOM). This instrument has been built and evaluated for the investigation of optical near fields in amplitude, phase and polarization. With ...
According to the present invention, it is provided an interactive device comprising a display, a camera, an image analyzing means, said interactive device comprising means to acquire an image with the camera, the analyzing means detecting at least a human ...
High-resolution infrared absorption spectroscopy of acetylene gas is demonstrated in dispersion-engineered photonic crystal waveguides under slow light propagation. Individual absorption profiles are obtained for both TE and TM polarizations for group indi ...
Society of Photo-Optical Instrumentation Engineers (SPIE)2012
Photonic crystals (PhC) are periodically structured electromagnetic media, in which light within some frequency ranges cannot propagate through the structure. Such frequency ranges are commonly referred as photonic band gaps (PBG). The length scale of the ...
High-resolution infrared absorption spectroscopy of acetylene gas is demonstrated in a dispersion-engineered photonic crystal waveguide under slow-light propagation. Experimental enhancement factors of 0.31 and 1.00 are obtained for TE and TM polarization, ...
The $40 “Wiimote” (an input device belonging with the Nintendo® Wii™ game system) can be used by hydrologists as a sensor. The device contains three accelerometers and an infrared camera with built-in source tracking. It communicates by Bluetooth®. Because ...
A miniaturized circular vertical Hall device with 8 contacts was studied in terms of its sensitivity, biasing topologies and residual offset. The geometry accounts for about 30% lower sensitivity, but offers the possibility of biasing the whole device in a ...
