    摘要： An optical modulating element has a core layer and first and second cladding layers sandwiching the core layer. The core layer is made of one or semiconductors belonging to a point group 43m or 42m, and has TM.sub.00 and TE.sub.00 propagation modes. The direction of light of said TM.sub.00 and TE.sub.00 propagation modes is parallel to the [110] or [-110] direction of crystal orientation. The change amount of an index of refraction of the core layer caused by the application of an electric field to the core layer in the direction parallel to the [001] direction is different for the two propagation modes.

    摘要： A method for producing a polarizer patterned with a plural number of portions having a polarizing ability or direction of polarization comprising the first step of producing a surface oriented in a pre-determined direction on a substrate, the second step of producing a polymerizable molecular layer which comprises polymerizable molecules on the above surface, the third step of polymerizing the molecules in said polymerizable molecular layer into a desired pattern and the fourth step of removing the unpolymerized portion of said polymerizable molecular layer. For example, the following procedure is repeated on one surface of a substrate to be given a polarizing ability: (1) An organic thin film uniformly oriented in a particular direction is produced by the Langmuir-Blodgett method, (2) a polymerizable molecular layer is produced on the above thin film, (3) the molecules in the polymerizable molecular layer is polymerized into a desired pattern and (4) the portion left unpolymerized of the polymerizable molecular layer is removed. By this treatment, a polarizer having as many orientation directions as the number of repetitions is obtained. The orientational order can also be given by rubbing in place of the Langmuir-Blodgett method.

    摘要： A method for managing virtual links within a multiple protocol label switched network is provided. A virtual link which includes a set of links between two devices is regarded as a single entity by a control component of a label switching router. Each packet to be transported on the virtual link is labeled based on its assigned forwarding equivalence class. A specific label is bound to a corresponding forwarding equivalence class. Such packets can be forwarded onto any one of the links within the virtual link. To load balance the various links within the virtual link, different selected hash functions are used at selected times to apportion the packets. depending on the load conditions.
