An optical element may include a substrate including a diffractive structure having multiple periods, at least one period of the multiple periods having multiple steps, heights of the multiple steps non-monotonically increasing across the at least one period. The optical element may be used with at least two wavelengths, e.g., three wavelengths, may be on a single surface and may provide an efficiency of at least 50% for all wavelengths.

Embodiments are directed to a system that may include a table with multiple user stations, a touch screen embedded in a top surface of the table, a table computer connected to the touch screen, and at least two mobile device connectors connected to the table computer and configured to be connected to a secondary screen viewable from the multiple user stations, wherein touching the touch screen at appropriate locations results in selection of content from a mobile device connected to the first mobile device connector, content from a mobile device connected to the second mobile device connector, and content from the table computer to be sent to at least one of the touch screen and the secondary screen for display thereon, and touching the touch screen at other appropriate locations results in another function in addition to selection of content for display.

An optical chassis includes a mount substrate an optoelectronic device on the mount substrate, a spacer substrate, and a sealer substrate. The mount substrate, the spacer substrate and the sealer substrate are vertically stacked and hermetically sealing the optoelectronic device. An external electrical contact for the optoelectronic device is provided outside the sealing. At least part of the optical chassis may be made on a wafer level. A passive optical element may be provided on the sealer substrate or on another substrate stacked and secured thereto.

A power monitor for a light emitter uses an absorptive material placed in the path of the application beam. The absorptive has a measurable characteristics thereof altered by an intensity of the light beam, the absorptive material being thin enough to allow a portion of the light beam sufficient for a desired application to be passed to the desired application. Preferably, an anti-reflective coating is placed between the absorptive material and the light emitting device. The absorptive material may be formed directly on the light emitting device or may be formed on or integrated with a spacer.
