摘要： A system and method for a structure monitoring and locating a disturbance event is disclosed. The system includes a compact transceiver chip sending optical signals in three optical fibers that encompass the monitored structure appropriately. The fiber arrangement has different density in different parts of the monitored structure, such as, for example, critical places in the structure may have larger number of fiber loops surrounding them. All fibers transmit signals in both directions: from the transceiver to a returning point and back. A set of two detectors registers the returning signals, and a time delay between those signals is calculated, which is indicative of the disturbance event location. Polarization states of the returning signals are controlled by transceiver built-in controllers. The event location is determined with different sensitivity in different parts of the monitored structure depending on the density of fibers in these parts.

摘要： Proposed optical device is based on counter-propagating optical fields within at least one nested waveguide-cavity loop, where the part of the waveguide loop is fold into the external waveguide loop. The nesting is performed using at least one waveguide crossing section. The invention may be used in Sagnac interferometer to measure various physical parameters, including rotation rate, electric current and mechanical perturbations. The invention also addressed a measurement method of such non-reciprocal parameters of interest. Optionally, the cavity includes a gain element, and the device operation may be switched discretely or gradually between passive and active regimes, thus changing the measurement characteristics.

摘要： Electro-optical method and device for modulation of light are presented providing a substantially balanced voltage-phase response of the device in two orthogonal polarization directions substantially irrespective of applied voltages. The device comprises a crystal material of a predetermined orientation of the plane of propagation of light therethrough, formed with at least one waveguide channel directed in a predetermined direction, and at least two electrodes accommodated at opposite sides of the waveguide channel. The substantially balanced voltage-phase response is achieved by shifting the electrodes relative to the axis of the waveguide channel a predetermined distance in a certain direction. The device may be designed so as to operate as a phase modulator or an amplitude modulator.
