A 4×4 fully non-blocking switch on SOI based on interferometric thermo-optic phase shifters

We developed a 4×4 fully non-blocking crossbar switch fabric based on interferometric thermal phase shifters, where heating is achieved using resistive elements around the silicon waveguide. We achieved switching times of 5 μs, with 41 mW power consumption in an individual switching element.

Antenna Beam Steering Without Phase Shifters – an ‘Old’ Technique Revisited

Antenna arrays are of perennial interest and relevance to RF wireless system designers, indeed the rise of 5G is showing their importance is only growing. Most implementations of linear arrays use phase shifters to feed the array and hence form the main-lobe beam. In the 1960s, a technique using RF switches and Fourier analysis was discovered to be a viable alternative to phase shifters called ...

Flexible, phase-transfer catalyzed approaches to 4-substituted prolines.

A range of 4-substituted prolines can be rapidly synthesized from a protected glycine Schiff base in only four steps and in 27-55% overall yield. Phase transfer catalysis allows direct access to both enantiomeric series, and the relative stereochemistry at the 4-position is readily controlled (>10:1 dr) through the choice of hydrogenation conditions.

Guided resonance reflective phase shifters

We present reflective phase shifters based on high contrast gratings resting on a low-index spacer backed by a metallic mirror. The guided resonance of the grating combined with the reflection from the metallic mirror leads to an all-pass filter with 2π phase shift variation and unity reflectivity across the resonance. We present simulations, fabrication and measurement of passive devices fabri...

Robotic Butler : Phase 1 Nsf

The contents of this report describe the specifics of a project aimed to program a “domestic” robot to follow an individual or specified target using sensor technology. Ultimately, the target will be, though not restricted to, the “Smart Chair,” a wheelchair that facilitates physically handicapped citizens with speaking and maneuvering. This would be of significant assistance to those with phys...
