Latest Patents

Robinson holds a patent for a "Method for locally modifying the effective bandgap energy in indium gallium arsenide phosphide (InGaAsP) quantum well structures." This novel quantum well intermixing method allows for the regional modification of bandgap properties in InGaAsP quantum well structures. The technique induces bandgap wavelength blue shifting and creates deep states that reduce carrier lifetime within these structures. This method is particularly applied to the modulator section of an integrated DFB laser/electro-absorption modulator, resulting in fast switching times and efficient optical coupling between the DFB laser and modulator region.
