Abstract: The physical limit for the number of pixels per color channel per frame in an optical imager is approximately equal to the aperture area in square microns. While this limit is essentially achieved in megapixel scale cell phone cameras, the limit of 100 megapixels for cm apertures, 10...

Abstract: The fate of an ultrashort laser pulse propagating in air depends crucially upon its peak power. Below a critical value, Pcr, group velocity dispersion and beam diffraction combine to rapidly reduce the pulse intensity. On the other hand, if P is less than Pcr, a completely different...

Abstract: Organic semiconductor materials offer the potential of low-cost and flexible displays and lighting solutions, some of which have already made it to the marketplace. Despite this, much of the underlying optical physics remains poorly understood and hinders progress towards better and...
