31036 – Solid state lighting, the use of electron to photon conversions in semiconductors, has proven itself an extremely efficient and robust avenue for the realization of many miniature display needs. Unfortunately, due to the nature of semiconductors, only the generation of individual colors is possible. One must, therefore, design with several different materials for each color desired. Also, for... Read More
30936 – It is known that by illuminating rare-earth materials, with invisible infrared light, reradiated light at specific visible wavelengths (or colors) is possible. This process, known as frequency up-conversion, has been applied to many technologies and now researchers at UCF have taken this interesting physical result and applied it to high resolution display. Using semiconductor device... Read More
32389 – Current linear modulators offer limited bandwidth and spurious-free dynamic range (SFDR) as electro-optic modulators and power handling as directly modulated lasers—also incurring high insertion loss and high Vpi. Recently developed at UCF, a new linear modulator with potentially infinite SFDR and multi-gigahertz bandwidth offers possible negative insertion loss and very low Vpi, in the range... Read More
32843 – Improve radar, communications, and signal intelligence with interferometer-based optoelectronic oscillator Optoelectronic oscillators (OEOs) provide a continuous, high quality factor (Q) modulated signal in order to obtain high spectral purity. OEOs are used for a variety of purposes, including a carrier wave for communications, and radar emissions. Most OEOs use an RF filter as the mode... Read More
