  • Patent number: 11953389
    Abstract: An optical sensing system including an optical interrogator is operative with an array of reflective sensors, each sensor providing a separable reflected spectral response parameter such as a unique Gaussian standard deviation or reflected response compared to other sensors in the same operating wavelength range. The optical interrogator provides narrowband swept or broadband continuous optical power source to the array of FBG sensors, and an optical interrogator generates a g(x) representation of power vs wavelength of the reflected optical power and decomposes the representation into the wavelength of the individual sensors, thereby allowing operation of two or more FBG sensors in the same operating wavelength range.

  • Patent number: 11860415
    Abstract: Integrated optical waveguides, direct-bonded waveguide interface joints, optical routing and interconnects are provided. An example optical interconnect joins first and second optical conduits. A first direct oxide bond at room temperature joins outer claddings of the two optical conduits and a second direct bond joins the inner light-transmitting cores of the two conduits at an annealing temperature. The two low-temperature bonds allow photonics to coexist in an integrated circuit or microelectronics package without conventional high-temperatures detrimental to microelectronics. Direct-bonded square, rectangular, polygonal, and noncircular optical interfaces provide better matching with rectangular waveguides and better performance. Direct oxide-bonding processes can be applied to create running waveguides, photonic wires, and optical routing in an integrated circuit package or in chip-to-chip optical communications without need for conventional optical couplers.
