Method and Structure for Optical Coupling in Photonic Integrated Circuits Using Etched Silicon Substrates
This invention introduces a novel method and structure for optical coupling in photonic integrated circuits (PICs) using etched silicon substrates. These etched features allow light to be introduced from beneath the substrate and efficiently coupled into on-chip waveguides. It enhances the efficiency of photonic couplings, allowing multiple input modes...

ON-OFF Perimetry
An innovative method to measure and characterize visual deficits in the ON-pathway and OFF-pathway in diseases affecting the visual pathway. Background: Perimetry is a systematic measure of visual field function, i.e., the area where stimuli can be seen in peripheral vision while the eye is fixed on a central point. In clinical settings, e.g. neurology,...
