Conventional optical components such as lenses, waveplates and holograms rely on light
propagation over distances much larger than the wavelength to shape wavefronts. In this …

This article presents the flip-chip bonding of vertical-cavity surface-emitting lasers (VCSELs)
to silicon grating couplers (GCs) via SU8 prisms. The SU8 prisms are defined on top of the …

Many interfacial properties are governed by both their surface chemistries and topologies. In
particular, surface patterning is gaining rapid momentum since last decade to aid in the …

Measurements of the angle-dependent ablation rates of polymers that have applications in
microdevice fabrication are reported. A simple model based on Beer's law, including plume …

The appropriate choice of glazing in a facade depends on many factors. They include
amongst other criteria: location, orientation, climatic condition, energetic efficiency, usage of …

Light redirecting devices usually increase the daylight illuminance level far from the window
but also affect the visual comfort to some extent. Some designs achieve high redirection rate …
