    摘要： A dynamically tunable filter controls the magnitude of couplings between core and cladding modes of a waveguide by surrounding the waveguide with an overcladding having an adjustable refractive index. The coupled modes are attenuated along the core to produce the desired spectral response. The adjustment to the overcladding index is made in a range that is above the refractive index of the underlying cladding to vary amplitudes of attenuated bands of wavelengths without shifting central wavelengths of the bands.

    摘要： The present invention relates to a tunable optical device 10 that includes an optical fiber device 12 having optical properties that vary with temperature and a heater 14. The heater 14 is thermally coupled to the optical fiber device 12. The heater 14 includes a metal layer 18 and two electrical contacts 20, 22 that are electrically connected to the metal layer 18. The electrical contacts 20, 22 are spaced apart from one another along the metal layer 18. The electrical resistance of the portion of the metal layer 18 between the contacts 20, 22 varies with temperature and serves as a resistive heater. The invention also includes a controller 16 that is electrically connected to the heater 14. The controller 16 provides electrical power to the heater 14 and measures the electrical voltage across the heater 14. The controller 16 compares the measured electrical voltage to a pre-selected reference value. The controller then regulates the amount of electrical current supplied to the heater 14. By regulating the amount of electrical current supplied to the heater 14 the temperature of the heater 14 is controlled.

    摘要： An optical module for interconnecting two or more optical fibers has a microreplicated waveguide element which is integrally formed on the same substrate with a splice element. In one embodiment, the module has three plates, a bottom plate, a cover plate, and a top plate, all contained within a common housing. The bottom plate has fiber-receiving grooves and fiber alignment grooves at its ends, the fiber alignment grooves being aligned with waveguide channels formed on the central portion of the bottom plate. The cover plate is used when forming the cores of the waveguide channels, to force residual curable, waveguide material into flow channels adjacent the waveguide channels, and this material, when cured, adheres the bottom and cover plates together. The top plate is used to clamp fibers which are held in the fiber alignment grooves, with the center of the fibers aligned with the core of the waveguide channels. The module housing includes wedges which may be independently actuated to secure the fibers, in a remateable fashion, to either end of the module.
