A multimode interference semiconductor optical amplifier (MMI-SOA) determines the output port with the input port and intensity-modulation of the CW light with the optical input signal. A first output port guides the converted signal, and a second output port guides the optical input signal.

    摘要: The present invention relates to an optical deflector driven by an electrical signal, and a wavelength tunable external resonator using the same. The optical deflector of a triangle shape, capable of controlling the refractive index of a beam depending on the electrical signal, is positioned between a reflection mirror and a diffraction grating in a Littman-Metcalf mode external resonator or between a lens and the diffraction grating in a Littrow mode external resonator. Thus, even with the reflection mirror and the diffracting grating fixed, the refractive index of the beam generated from a laser diode can be controlled by adjusting the electrical signal applied to the optical deflector, so that beam having a specific wavelength can be focused and the wavelength can be rapidly and consecutively tuned.

    摘要: A virtualization apparatus includes: an emulation manager for searching a basic block cache for an entry with an entry point, and, if there exists no entry with the entry point in the basic block cache, requesting the identification of a basic block corresponding to the entry point; a basic block identifier for identifying the basic block by sequentially analyzing instructions of a source binary in response to a request from the emulation manager; and an instruction replacer for writing an entry of the identified basic block in a replaced instruction table, writing a branch instruction for the entry of the basic block in the source binary, and then branching to the entry point. The apparatus further includes an instruction emulator for executing an instruction of the basic block when a branch to the entry point is made.

    摘要: Provided are a network scheduler and a network scheduling method capable of effectively managing network bandwidths by selectively supporting a work conserving mode to network entities by using an improved token bucket scheme. The network scheduler selectively supports a work conserving mode to network scheduling units (NSUs) serving as network entities by using a token bucket scheme, such that the network scheduler ensures an allocated network bandwidth or enables the NSUs to use a remaining bandwidth. The network scheduler manages the NSUs by classifying the NSUs into a green state, a red state, a yellow state, and a black state according to a token value, a selection/non-selection of the work conserving mode, and an existence/non-existence of the packet request to be processed.

    摘要: A data transfer apparatus, system and method using the same are provided. A data transfer system according to an exemplary embodiment includes a user process space, a kernel space and a hardware space. A plurality of user processes are executed in the user process space. The kernel space includes a kernel thread. The hardware space performs an input/output according to the input/output request of the each user process. When input data based on the input request are received to the hardware space, the data transfer system checks whether the user process requesting the input is in an execution state, and allows the kernel thread to copy the input data from the kernel space to the user process space when the user process is in the execution state.
