摘要： A fiber-optic address detector comprises fiber-optic delay lines on one surface of which a metal thin film is evaporated, the fiber-optic delay lines being connected in a melting state to fiber-optic couplers, wherein inputting address photonic signals are tapped by the inputting fiber-optic couplers, reflected by the metal thin films at the end portion of the fiber-optic delay line and then re-combined by the inputting fiber-optic coupler, whereby it can reduce the number of the fiber-optic coupler used in the conventional fiber-optic address detector to one half as well as obtain the same address detection effect.

摘要： A novel, monolithically integrated mid-IR optical phased array (OPA) structure which eliminates the wafer bonding process to achieve highly efficient surface emitting optical beam steering in two dimensions is disclosed. Since solar energy is about 15-20 times smaller than that at 1.55 um, mid-IR is more favorable for the atmospheric transmission due to lower solar radiance backgrounds. For the beam steering, thermo-optic phase shifting is used for azimuthal plane beam steering and laser wavelength tuning is used for elevation plane beam steering. The OPA structure disclosed comprises a wavelength- tunable a QCL, a 1×32 splitter, thermo-optic phase-shifters, and sub-wavelength grating emitters. The disclosed OPA provides a low-cost, low-loss, low-power consumption, robust, small footprint, apparatus that may be used with expendable UAV swarms. A LiDAR may be created by monolithically integrating a QCD with the apparatus. Other embodiments are described and claimed.

摘要： Apparatus and method for scheduling transmission of data bursts in an OBS network are described. One embodiment is a router in an OBS network, the router comprising a grouper module for collecting a group of BHPs arriving during a BHP collecting period and classifying each BHP of the group of BHPs into corresponding baskets depending on the data channel scheduling window of its corresponding data burst; a classifier and channel assignment module for assigning data bursts to appropriate data channels; and a channel scheduler for constructing an interval graph representing data bursts corresponding to BHPs classified in a single one of the baskets having overlapping segments on each data channel as adjacent vertices and scheduling data bursts on each data channel based on a process that finds a maximum number of non-adjacent vertices on the interval graph.
