摘要： A True Time Delay system for creating variable time delays of an optical signal suitable for use with a phased array antenna system in order to avoid beam-squint in broadband applications. The TTD is adapted to be integrated on a planar silica waveguide in order to substantially reduce the package size of the device. In one embodiment of the invention, the TTD is formed from a polarization beam splitter, a polarization rotator and a spiral waveguide. In an alternate embodiment of the invention, the TTD includes a polarization sensitive Mach Zehnder interferometer, a quarter wave polarization rotator and a spiral waveguide. In both embodiments of the invention Bragg reflective gratings are written into the spiral waveguide at different spacings to reflect optical signals of different wavelengths to create various time delays.

摘要： An orthogonal pilot tone servo controller provides a servo control loop for each tap in a delay line processor where each servo acquires its independence from the other tap's servos utilizing an orthogonal code set modulated on top of the existing tap values. The orthogonal codes are attenuated in amplitude such that the code sets are transparent to the processed signals of interest, but the code's length enables each tap's servo controller to independently recover the tap's state from the aggregate of signals and codes through processing gain realized in each loop's recovery circuit. A plurality of taps can be thus be servo controlled simultaneously, providing for extremely wide bandwidth processes which can be performed accurately with digital controls.
