摘要： A rare-earth doped glass waveguide is optically pumped to produce superfluorescent light. The waveguide is formed in a glass substrate. The pump light is input to a first end of the optical waveguide, and the output is emitted from the other end. A grating formed on the waveguide near the output end reflects the pump light to separate the pump light from the output light.

摘要： The cladding and a portion of the core of a length of optical fiber are removed to form an interaction region. A form birefringent stack is positioned on the exposed core. The refractive index of the stack for polarizations parallel to the plane of the interaction region is approximately equal to the refractive index of the fiber core so that these polarizations radiate from the fiber. The refractive index of the stack for the polarization normal to the plane fo the interaction region is approximately equal to the refractive index of the cladding so that this polarization remains guided by the fiber. A photodetector forms an error signal from the polarization radiated from the fiber, and control circuitry processes the error signal to drive a polarization controller that adjusts the polarization of light input to the polarizer to minimize the error signal.

摘要： This invention is a frequency shifter for receiving an optical carrier signal input and producing an output including a sideband that is shifted in frequency from the carrier. The frequency shifter includes an optical waveguide formed in a substrate of an electro-optically active material such as lithium niobate. A plurality of electrodes formed on the substrate cooperate with a signal generator to apply two perpendicular electric fields to the optical waveguide. The resultant of the two fields is a rotating electric field which produces a rotating birefringence in the optical waveguide. The rotating birefringence acts as a rotating wave plate, which shifts the frequency of optical signals input to the optical waveguide. The wave plate is preferably a half wave plate, which converts all of the input optical energy into the sideband.

摘要： A transmission mechanism for an electrical nail gun includes a rotary transmission unit and a linear transmission unit in a housing of the electrical nail gun. The rotary transmission unit includes a motor driven by electricity, a flywheel driven by the motor and extending to form a cylinder thereon, a solenoid activated by electricity, and a moveable driving wheel adjacent to an end side of the cylinder. A clutch is formed between the cylinder and the driving wheel. The solenoid is buried in the cylinder so that a magnetic conductivity loop is constructed around the solenoid to produce the magnetic field when the solenoid is activated. The driving wheel is attracted to move to an engagement position to be driven by the flywheel, thereby driving the linear transmission unit to impact a nail when the solenoid is activated by electricity, and the driving wheel returns to a disengagement position to disengage from the flywheel, thereby stopping driving the linear transmission unit when the solenoid is demagnetized.

摘要： A polarizing optical fiber has a core formed of a plurality of layers of dielectrics having different refractive indices. The dielectric layers form a composite structure having different refractive indices for light of different polarizations. The differing refractive indices cause the polarization states of light guided by the fiber to be non-degenerate so that energy ordinarily will not couple from one polarization to the other. The fiber includes a cladding that may have a refractive index either less than both core indices to provide a polarization maintaining fiber or greater than or equal to one of the core indices to provide a polarizing fiber. The method of fabrication of the layered core form birefringent optical fiber includes forming a structure of a plurality of layers of the dielectrics, heating the structure to form a monolith, stretching the monolith to form the fiber core, and adding the cladding to the core.
