Title: Prosthetic vision with a photovoltaic substitute for the lost photoreceptors Abstract: Retinal degenerative diseases lead to blindness due to loss of photoreceptors, while neurons in the inner retinal layers are still preserved. We developed a system substituting the lost photoreceptors with photovoltaic arrays. Visual information captured by a camera is projected onto the subretinal implant from augmented-reality glasses using pulsed …
CREOL CalendarMikael RechtsmanPhysics Department, Penn State University Tile: Two experiments on aperiodic photonic crystals Abstract: Photonic crystals -- transparent periodic dielectric structures -- have been called "semiconductors for light" in the sense that photons propagate through them much as electrons propagate through crystalline solids. In the first part of my talk, I will show how straining a photonic crystal can make photons …
