A novel optical waveguide for integrated optics
IEEE Journal of Quantum Electronics, 1973A novel dielectric optical waveguide was made consisting of a guide pattern on a thin dielectric film. Almost all the power propagates in the thin film along the guide pattern. The existence of propagation modes of this waveguide was verified both theoretically and experimentally.

Long-distance quantum communication with atomic ensembles and linear optics
Nature, 2001Quantum communication holds promise for absolutely secure transmission of secret messages and the faithful transfer of unknown quantum states. Photonic channels appear to be very attractive for the physical implementation of quantum communication ...

Nonlinear optics and optical activity
Journal of Physics C: Solid State Physics, 1972The second-harmonic generation coefficients of sodium chlorate and sodium bromate crystals are estimated from their optical rotatory powers by means of the anharmonic oscillator model of Condon, Altar and Eyring. The correct signs are determined, and reasonably good numerical agreement with experiment is obtained.

All Optical Processing of Optical Packets
Asia Communications and Photonics Conference and Exhibition, 2009In this paper two different paradigms to realize a scalable all-optical packet switch with label swapping will be reviewed. All the functions required for switching the packets are based on all-optical signal processing without any electronic control. This allows very low latency and potential photonic integration of the systems.

The optic chiasm is formed when the optic nerves come together in order to allow for the crossing of fibers from the nasal retina to the optic tract on the other side. This enables vision from one side of both the eyes to be appreciated by the occipital cortex of the opposite side.

Physical Optics, Wave Optics, and Fourier Optics
1991When any of the dimensions or sizes of the components in an optical system is on the order of wavelength, then the methods discussed under geometrical optics do not give the proper solution to the problem. For this case, we must start from Maxwell’s equations, and derive the wave equation from which the proper solution to this problem can be obtained.

Optic Nerves, Optic Chiasm, and Optic Tracts
1988The vertebrate optic nerves, optic chiasm, and optic tracts contain axons of retinal ganglion cells. These axons connect the retina, where light absorption produces patterned neuronal firing, to the brain, where these firing patterns can undergo further processing.

Optical Systems and Statistical Optics.
1982Abstract : Theoretical and experimental research is being conducted in the field of opto-electronic systems. The goal is to contribute solutions to problems of basic research importance which also have an underlying significance in practical applications that involve automatic pattern recognition and remote sensing.
