    • An optical waveguide to fiber coupler comprises a substrate, a first waveguide and a second waveguide. The first and second waveguides are formed on the substrate and intersect at a right angle. A diffraction grating structure is formed at the intersection of the first and second waveguides, such that, when the coupler is physically abutted with a single mode optical fiber, in operation, a polarization split is obtained that couples orthogonal modes from the single-mode optical fiber into single identical modes in the first and second waveguides. Also, employing the coupler in optical polarization diverse applications provides for implementing a polarization insensitive photonic integrated circuit using such diffraction grating structures, such as, for example, photonic crystals.
    • 光波导到光纤耦合器包括衬底,第一波导和第二波导。 第一和第二波导形成在基板上并以直角相交。 衍射光栅结构形成在第一和第二波导的相交处,使得当耦合器物理地与单模光纤相接时,在操作中获得偏振分裂,其将来自单模光学 光纤在第一和第二波导中成为单个相同的模式。 此外,采用光学偏振多种应用中的耦合器提供了使用这种衍射光栅结构(例如光子晶体)实现偏振不敏感的光子集成电路。

    • A method for programming a single bit nonvolatile memory cell integrated on a metal-dielectric-semiconductor technology chip. The memory cell comprises a semiconductor substrate including a source, a drain, and a channel in-between the source and the drain. The memory cell further comprises a control gate that comprises a gate electrode and a dielectric stack. The gate electrode is separated from the channel by the dielectric stack. Further, the dielectric stack comprises at least one charge storage dielectric layer. The method for programming the memory cell comprises applying electrical ground to the source, applying a first voltage having a first polarity to the drain, applying a second voltage of the first polarity to the control gate; and applying a third voltage having a second polarity opposite to the first polarity to the semiconductor substrate.
