Latest Patents

George K Chik holds a patent for a semiconductor laser structure designed for improved stability of the threshold. This invention features a Type II heterojunction formed of semiconductor material that typically forms a Type I heterojunction. The Type II heterojunction is achieved by utilizing a carefully selected stack of epitaxial semiconductor materials, which modify the band structure through quantum mechanical confinement effects. This virtual Type II heterojunction is integrated adjacent to the active region in a single-quantum-well, ridge-waveguide laser structure. Notably, an anomalous 'Negative-T.sub.o' region is observed, where the threshold current decreases with increasing temperature. This results in a reduction in the temperature sensitivity of the threshold current of the laser structure.
