    • An improved electro-optical system has a planar waveguide coupled to a photodetector through a transparent substrate. The planar waveguide is within a planar optical structure that can be part of optical communication network. The photodetector is positioned to receive light that passes from the waveguide through the transparent substrate. The photodetector can be electrically coupled to electrical circuitry along the transparent substrate for connection to a electrical apparatus. Corresponding methods for forming the electro-optical structure are described. These improved electro-optical systems can be used for terminating an optical transmission system at an end user or a local network associated with a group of end users.

    • A linearized thermal and optical model of an optical integrated circuit can be used to temperature-stabilize one or more optical elements of the circuit using active temperature regulation. To stabilize a single optical element, such as an arrayed waveguide grating (AWG), a temperature sensor and a heater can be provided proximate to the grating. Thermal and optical coefficients can be then used to select an appropriate temperature set-point for the temperature controller that receives readings from the sensor and determines the power dissipated in the heater. Multiple AWG's can be stabilized individually, using the same process and lumping cross-heating factors together with other environmental factors. Alternatively, multiple AWG's can be stabilized using fewer sensors than AWG's, by stabilizing one of the AWG's in the same manner as in the case of a single AWG, and determining power dissipated in the heaters of the remaining AWG's based on the linearized model.
    • 可以使用光学集成电路的线性化热和光学模型来使用主动温度调节来温度稳定电路的一个或多个光学元件。 为了稳定单个光学元件,例如阵列波导光栅(AWG),可以在光栅附近提供温度传感器和加热器。 然后可以使用热系数和光学系数为温度控制器选择适当的温度设定点,该温度控制器从传感器接收读数并确定加热器中消耗的功率。 多个AWG可以单独稳定,使用相同的过程并将交叉加热因子与其他环境因素结合在一起。 或者,通过使用比AWG更少的传感器,可以使用比AWG更少的传感器来稳定多个AWG,通过以与单个AWG相同的方式稳定AWG之一,并根据线性化模型确定剩余AWG的加热器中消耗的功率。

    • According to one embodiment of the present invention, a method for integrating client and server deduplication systems may be provided. In this method, a first hash set of a previous backup session may be received from a server. The first hash set may comprise a plurality of cryptographic values generated using a plurality of data blocks of a first data set of a client. A second hash set may be generated using a plurality of data blocks of a second data set of the client. A deduplicated data set may be generated by the client according to the first hash set and the second hash set and may comprise a plurality of non-redundant data blocks of the second data set. The second hash set and the deduplicated data set may be transmitted to the server.

    • The various embodiments herein include operate to identify, consolidate, and reduce redundant backup data storage. One embodiment includes storing data blocks and first signatures of data chunks of each stored data block, the first signature of each data chunk including a reference to a storage location of the data chunk within a stored data block, the stored data blocks including data blocks of previous and recent backup sessions. Some embodiments further include storing second signatures in a second signature repository, where the second signatures are calculated based on determined boundaries of the first signatures from previous backup sessions. At least one of the second signatures is calculated based on at least two first signatures, and in the range of 32 to 64 first signatures in some embodiments. Some embodiments may identify data chunks of the recent backup session present in the stored data blocks prior to the recent backup session.
