An ultrafast single-wavelength optically time-division multiplexed (OTDM) link is described. The link exploits a unique integrated, all-optical serial-to-parallel (S/P) converter based on second-harmonic generation that demultiplexes multiple high-sp

Normal-incidence planar-optical waveguide-imbedded phase gratings of finite aperture width and length are analyzed with Svidzinskii's (Sov. J. Quantum Electron. 10, 1103 (1980)] two-dimensional Braggdiffraction theory. Svidzinskii's characteristic-gr

A four-wave theory of phase gratings electrooptically induced in dielectric waveguides is analyzed and solutions to the coupled-wave equation are derived for incidence at the first Bragg angle. These solutions are compared with the solutions for the

An integrated optics (IO) device that is an implementation of an IO tapped delay line is discussed. It is capable of performing discrete convolution of an optical pulse sequence with a preset digital function. Several architectures for the device are

Summary form only given. We have previously proposed an ultrafast all-optical demultiplexer based on surface-emitted second-harmonic generation (SESHG) for optically time-division multiplexed (OTDM) communications. This scheme is advantageous in that

Proceedings of the 1991 IEEE National Radar Conference.
An integrated optic time delay unit (TDU) is described. The TDU relies on a folded path optical waveguide to achieve time delays ranging from a few picoseconds to several nanoseconds. The folded path configuration utilizes thick phase gratings as ref

Nonlinear Guided Waves and Their Applications.
We combine multimode interference (MMI) and self-guiding to create optical switching and limiting devices. Operation depends upon the light-intensity-controlled switching between the MMI and the self-guiding modes of operation.
