Integrated optics is a field of study and technology that focuses on the design, fabrication, application optical devices systems using integrated circuit technology. It involves integration various components, such as waveguides, couplers, modulators, detectors, lasers, into single substrate. One key advantages its compatibility with electronic circuits. This enables seamless functionalities o...

Gratings with variable periods (chirped gratings) have been fabricated by recording the interference pattern of a collimated laser beam with a converging beam generated by a cylindrical lens. An analysis is presented for the behavior of the chirped gratings as a function of wavelength, the angle between the illuminating beams, the F number of the lens, and its position. To calculate the power r...

Thin-film dielectric waveguides with a periodic refractive index, a periodic substrate, or periodic surface are studied. The field is determined from Maxwell's equations using Floquet's theorem. The Brillouin diagram and the interaction regions are investigated. The bandwidth and the attenuation coefficients of the interaction regions are given as a function of the optical wavelength. A number ...

We report a novel surface-micromachined micro-optical bench (MOB) technology which enables us to monolithically integrate "flipped-up" free-space optical elements with micro-positioners and micro-actuators. This technology allows complete optical systems be implemented on a single Si chip using IC-like microfabrication processes. We have, for the first time, successfully fabricated micro-Fresne...

I . INTRODUCTION Integrated optics (IO) devices for application in telecommunication are highly demanding on low insertion loss, efficient fiber-to-chip coupling, high compactness (small bending radii) and polarization independent operation. In most operating communication devices developed within the last decade, low-index contrast waveguiding structures have been applied El]. The large channe...

We show that arbitrary family of universal quantum gates can be implemented in integrated optics based on single optical hybrid/Mach-Zehnder interferometer/directional coupler and highly nonlinear optical fibers (HNLFs). We also show how to implement the Bell states preparation circuit and quantum relay, needed in quantum teleportation systems, using the same technology. Finally, we study the i...

This paper deals with the theory and device applications of periodic thin-film waveguides. Topics treated include mode solutions, optical fiiters, distributed feedback lasers (DFB), distzibuted B r a g reflector (DBR) lasers, grating couplers, and phase matching in nonlinear interactions.

Three-dimensional direct-write lithography can be used to pattern waveguides into diffusion photopolymer using low-power CW lasers as an alternative to femtosecond writing in glass. We show that polymer chemistry permits significant control of waveguide shape. © 2005, Optical Society of America OCIS Codes: (130.3120) Integrated optics devices, (160.2900) Holographic recording materials, (130.31...

We examine limitations of carrier removal with a p-n junction in Raman devices, namely, ineffectiveness at high optical intensities due to the applied field being screened, electrical heat dissipation, and the possibility of thermal instability. © 2006 Optical Society of America OCIS codes: (130.3120) Integrated optics devices, (190.4390) Nonlinear optics, integrated
