A new process and structure for microcomponent interconnection utilizing a post-assembly activated junction compound. In one embodiment, first and second microcomponents having respective first and second contact areas are provided. A junction compound is formed on one of the first and second contact areas, and the first and second contact areas are positioned adjacent each other on opposing sides of the junction compound. The junction compound is then activated to couple the first and second microcomponents.

A device is described based on flexible photonic crystal, which is comprised of a periodic array of high index dielectric material embedded in a flexible polymer. Dynamic, real time tunability is achieved by the application of a variable force with a MEMS actuator or other means. The force induces changes in the crystal structure of the photonic crystal, and consequently modifies the photonic band structure. The concept was demonstrated by a theoretical investigation on the effect of mechanical stress on the anomalous refraction behavior of the flexible PC, and a very wide tunability in beam propagation direction was observed. Experimental studies on fabrication and characterizations of the flexible photonic crystal structures were also carried out. High quality flexible PC structures were fabricated by e-beam lithography and anisotropic etching processes.

A backlight unit includes light source units which emit light, and light source driving integrated circuits which control a brightness of the light source units, respectively. Each of the light source driving integrated circuits includes a current generator which generates a first current and a second current, a current level controller which controls a current value of the first current in response to duty ratio information of a pulse width modulation signal, a voltage supply unit which outputs a voltage corresponding to the second current, an output buffer unit which outputs the voltage from the voltage supply unit, and a driving switch unit which drives the light source units to allow a current corresponding to the voltage provided from the output buffer unit to flow through the light source units, where current values of the second current and the first current are the same as each other.

Highly-compliant polymer-based resonant diffraction gratings, and methods of use thereof, are provided. In one illustrative embodiment, an amount of pressure applied to a grating surface may be determined by straining a grating, adapted to move into a plurality of pitches, to an applied pitch in the plurality of pitches in response to an application of strain onto a surface adjacent the grating. Electromagnetic radiation comprising a plurality of wavelengths may be applied to the grating, and a resonance wavelength, in the plurality of wavelengths, may be identified while the strain is applied to the grating. The amount of strain applied to the grating surface may then be determined based on the resonant wavelength.
