Latest Patents
One of his latest patents is the "Optically controlled semiconductor waveguide interferometer apparatus." This invention includes a Mach-Zehnder interferometer formed of semiconductor laser materials. It features a first optoelectronic switching means coupled across a first voltage potential and one of the optical paths of the interferometer. The first optoelectronic switching means has a first gap, while a second optoelectronic switching means is adapted to be coupled across a second voltage potential and the other optical path, also having a respective gap. Light pulses are applied to the two gaps to control the index of refraction of the optical paths, allowing modulation of the output intensity of the interferometer.
Another significant patent is for "Methods of and apparatus for measuring picosecond semiconductor laser." This invention measures the duration of very short semiconductor laser pulses, ranging from fractions to hundreds of picoseconds. It utilizes the internally generated second harmonic emission of the laser. A laser diode is driven to emit light that passes through a beam splitter, reflecting into a photomultiplier and a detector. The apparatus includes a photodiode for measuring fundamental laser power and a photomultiplier for measuring second harmonic power, with ammeters coupled to measure the appropriate current.
