    • A chalcogenide glass composition composed of arsenic (As), selenium (Se), sulfur (S), and antimony (Sb) is presented. The composition includes arsenic in the range from 25% to 45% by weight relative to the total weight of the composition, selenium in the range from 40% to 65% by weight relative to the total weight of the composition, sulfur in the range from 2% to 15% by weight relative to the total weight of the composition, and antimony in the range from 0% to 15% by weight relative to the total weight of the composition.

The glass composition is preferred to have a thermal expansion coefficient of about 23.6×10−6/° C., a temperature coefficient of refractive index less than about 1×10−6/° C., a glass transition temperature less than 200 degrees Celsius, and/or a glass softening temperature less than 250 degrees Celsius. The present invention has immediate applicability within infrared sensors, infrared imaging devices, lasers, and fiber optic components, one example being amplifiers.

    • Optical switches which take multiple incoming optical signals and switch them to multiple output ports to realize multiple working states. For example, in a four by four switch embodiment, twenty-four working states can be selected. These switches rely on magneto-optically or electro-optically switching the beam polarizations from one state to another to rapidly change the light path. An optical signal is spatially split into two polarized beams by a birefringent element. These beams pass through a series of polarization rotation elements and recombine into output fibers, achieving polarization independent operation. A polarization beam splitter may be used as the key element to establish multi-port switching. Light bending devices that allow two fibers to be coupled to the light beams using a single lens may be used to achieve small fiber separation for compactness.

    • A method for HARQ reordering in Enhanced Uplink Dedicated Channel of WCDMA system includes following steps: locating the soft combination buffer in the Node B and the reordering buffer in the SRNC; locating the HARQ entity in the Node B; locating the reordering queue distribution entity, the reordering entity and the disassembly entity in the SRNC. This invention adopts the separation technology of the soft combination buffer and the reordering buffer, the separation model can not only ensure the diversity gain, but also reduce the receiving delay and save the buffer space. Three mechanisms (timer mechanism, window mechanism and SBI mechanism) are proposed to prevent the blocking of the reordering buffer, which degrades the blocking to the least level, improves the receiving efficiency and the system performance. Aiming at the SBI mechanism, the invention proposes the new DCH data frame structure on the Iub interface and the Iur interface.

    • The present invention provides improved optical switches in which no mechanical movement is required to direct optical pathways between plural fiber ports. Advantageously, the inventive switches incorporate two-stage polarization rotation to improve isolation depth, as well as temperature and wavelength independence. The inventive switches also incorporate light bending devices to allow two fibers to be coupled to the light beams using a single lens achieving small beam separation for compactness. In the inventive switch, an optical signal is spatially split into two polarized beams by a birefringent element, which passes through a polarization rotation device that comprises waveplates, walk-off elements, and electrically controllable polarization rotators, and recombine into an output fiber, achieving polarization independent operation. The switches of the present invention rely on electro-magnetically or electro-optically switching the beam polarizations from one state to another to rapidly direct the light path.

    • An optical modulator is provided to control the intensity of a transmitted or reflected light. In a transmission mode, a separator splits arbitrarily polarized light into two polarization rays and one is made to travel a separate path from the other. A recombiner causes the two rays to recombine at an output unless an electro-optic phase retarder changes the polarization of the two rays, in which case, both of them miss the output by an amount which is a function of the voltage on the retarder. A normally-off version with low polarization mode dispersion is obtained by changing the orientation of the recombiner. A normally-on version with low polarization mode dispersion is obtained with a passive polarization direction rotator. Similar results can be obtained in a reflection mode where the input and output are on the same side of the modulator. Versions using a GRIN lens are particularly suited to modulation of light out of and back into fiber-optic cables. The device can be operated as a variable optical attenuator, an optical switch, or a high speed modulator and is insensitive to polarization of the input light. A preferred material for the phase retarder is a hot-pressed ceramic lead lanthanum zirconate titanate composition.
    • 提供光调制器以控制透射或反射光的强度。 在透射模式中,分离器将任意偏振光分离成两个偏振光,一个偏振光从另一个行进。 重组器会导致两条射线在输出端重新组合,除非电光相位延迟器改变两个射线的极化,在这种情况下,它们都将输出误差减去延迟器上的电压的函数。 通过改变重组器的取向,获得具有低偏振模色散的常关型。 使用无源偏振方向旋转器获得具有低偏振模色散的常导版本。 在输入和输出位于调制器的同一侧的反射模式下可以获得类似的结果。 使用GRIN镜头的版本特别适用于调制光纤到光纤的光纤。 该器件可以作为可变光衰减器,光开关或高速调制器操作,并且对输入光的偏振不敏感。 用于相缓凝剂的优选材料是热压陶瓷铅锆酸镧锆酸盐组合物。
