Semiconductor Laser Source with Electrically Tunable Emission Wavelength
A tunable semiconductor with novel wavelength adjusting technology Background: An adjustable semiconductor light source, such as lasers or light diodes, have a high demand for variable wavelengths in a controllable manner. Although there are methods to change the wavelength of a light beam, they are either impractical or uncontrollable. There is a...

Compound Semiconductor Device on Virtual Substrate
Fabrication of infrared photo detectors with high quality and appropriate thicknesses. Background: The detectors for semi conductors must 1) have a low defect density 2) have complete control over alloy composition of the materials grown. However, traditional infrared photodetectors are created by elements in Group III or V of the periodic table,...

Bi Directional Dual-Color Light Emitting Devices
A technology that permits the generation of two wavelengths of light from a single LED where either wavelength can be active at any time. Background: Light emitting diodes (LEDs) are semiconductor devices that convert electrical energy into light. Like all diodes, they conduct electricity differently in one direction as compared to the other. A typical...
