A mirror for a mobile device, the mirror configured as a flexible multilayered laminate electrostatically and removably adhered to a viewing screen or other smooth surface of the mobile device. The laminate has at least one reflective layer adhered to an optically transparent bottom layer made of a plastic-silicone material. In another embodiment, the laminate includes a switchable film layer that when current is applied becomes optically opaque, allowing a split screen use of the viewing screen. For instance, when current is applied to the laminate, half of the viewing screen is a mirror and the other half allows use of software and other features of the mobile device. In yet another embodiment, a true mirror is created using software to create a reflective surface beneath a glass of the viewing screen. Control of the mirror using software and physical switches are also provided. LED lighting is also provided.

The brightness of a TIR-based display is enhanced with a registered reflective element by recycling and reflecting light that passes through the dark pupil region of each hemi-spherical protrusion in the hemi-spherical surface back to the viewer. A method to fabricate a brightness enhanced TIR display comprising an apertured membrane with a thin conductive reflective metal layer facing and registered with the pupils of the hemi-spherical surface.
摘要:
Devices and methods for lessening a thermal dependence of gain profile of an optical amplifier are disclosed. An optical beam is split in a plurality of sub-beams with a thermally variable power splitting ratio, e.g. one sub-beam may travel a longer optical path length than another. When the sub-beams are recombined, they interfere with each other, causing the throughput to be wavelength dependent. An amplitude of this wavelength dependence is thermally variable due to the thermally variable power splitting ratio. The thermally variable power splitting ratio and the optical path length difference are selected so as to offset a thermal variation of a spectral gain profile of an optical amplifier.
