Ultra low-loss low-efficiency diffraction gratings.
The realization of ultra low-loss dielectric reflection gratings with diffraction efficiencies between 7% and 0.02% is presented. By placing the grating beneath the highly reflective layerstack scattering was significantly reduced. This concept allows the all-reflective coupling of high laser radiation to high finesse cavities, thereby circumventing thermal effects caused by absorption in the s...
متن کاملSwitching Techniques: Concepts for Low Loss Switching
Highlighting the dominance & supremacy of CMOS digital logic design over its counterparts & further coming up with a unique solution to minimize the power losses prevalent in switching implementations using CMOS, this brief introduces a novel SDLC (Switching-DiodeInductor-Capacitor) design. It presentsa design which in ideal case may lead to a circuit capable of performing logic operations with...
متن کاملThin low-loss dielectric coatings for free-space cloaking.
We report stereolithographic polymer-based fabrication and experimental operation of a microwave X-band cloaking device. The device is a relatively thin (about one wavelength thick) shell of an air-dielectric composite, in which the dielectric component has negligible loss and dispersion. In a finite band (9.7-10.1 GHz), the shell eliminates the shadow and strongly suppresses scattering from a ...
متن کاملSurface plasmon enhanced diffraction for label-free biosensing.
Surface plasmon enhanced evanescent field at a (noble) metal/dielectric interface can be employed to enhance the diffraction efficiency of surface grating structure composed of biomolecules. Based on a Kretschmann configuration, we realized a diffraction biosensor to monitor the dynamic interaction of biological molecules in a label-free way. It was demonstrated by the binding of an anti-biotin...
متن کاملDiscrete-like diffraction dynamics in free space.
We introduce a new class of paraxial optical beams exhibiting discrete-like diffraction patterns reminiscent to those observed in periodic evanescently coupled waveguide lattices. It is demonstrated that such paraxial beams are analytically described in terms of generalized Bessel functions. Such effects are elucidated via pertinent examples.
