  • Photonic input/output port
    Patent number: 7269326
    Abstract: The present I/O ports comprise (1) a layered structure comprising (a) an unpatterned superstrate having at least one layer, (b) an unpatterned substrate having at least one layer, and (c) at least one intermediate layer sandwiched between the unpatterned superstrate and the unpatterned substrate, (2) a coupling region that is within the at least one intermediate layer and that comprises an arrangement of at least one optical scattering element and (3) at least one output waveguide. The present I/O ports can be effectively used in balanced photonic circuits and unbalanced photonic circuits.

  • Planar photonic bandgap structures for controlling radiation loss
    Patent number: 6684008
    Abstract: The present planar photonic bandgap structures achieve improved control over radiation losses by employing layered dielectric structures. These structures control radiation losses incurred in connection with planar photonic bandgap structures and waveguides, waveguide bends, waveguide crossings, filters, switches and fiber-coupling structures in which such planar photonic bandgap structures are used.

  • Electric field detector
    Patent number: 4386315
    Abstract: Apparatus for detecting electric fields and providing an indication of their magnitude includes a glass bulb containing a gas such as neon. When the bulb is placed in a time varying electric field, pulses of electromagnetic radiation are generated within the bulb. The number of pulses is proportional to the magnitude of the variation in the electric field. The pulses are transmitted by a fibre optic bundle to detection and recording apparatus to provide an indication of the magnitude.
