Si wire waveguide devices

SPIE Proceedings, 2007
This paper presents our recent progress in the development of a Si wire waveguiding system for microphotonics devices. We have developed function devices that integrate several fundamental components and confirmed that they exhibited excellent characteristics due to the accuracy of the Si microfabrication.

Advances in polymer waveguide devices

The 16th Annual Meeting of the IEEE Lasers and Electro-Optics Society, 2003. LEOS 2003., 2004
Material and fabrication advances have brought polymer high speed, low voltage EO modulators close to commercial development. The technology is now being applied to more complex photonic switches and circuits and we will review some of the latest applications of polymers in photonics. We will briefly review the state of the art for high band-width, low

Waveguiding effect on modal gain in optical waveguide devices

IEEE Journal of Quantum Electronics, 1991
The waveguiding effect on modal gain in narrowly confined structures in optical waveguide devices, such as semiconductor laser diodes, is discussed. It is shown that a difference exists between the rigorous modal gain derived from the wave equation and the approximate modal gain used in the literature. This difference means that there is an enhancement

Silicon Photonic Waveguides and Devices

Conference on Lasers and Electro-Optics/International Quantum Electronics Conference, 2009
Several silicon photonic waveguide geometries for both near- and mid-infrared wavelength regions are presented. These waveguides are basic building blocks of more complex photonic circuits such as modulators, detectors, filters, couplers or light sources. In this paper, the application of waveguide structures in both passive and active devices is given.

Microwave device on square waveguide

Fifth International Conference on Actual Problems of Electron Devices Engineering, 2003
Microwave device which contains a square cross section shaped waveguide as a basic unit of travelling wave applicator with two dominant modes H/sub 10/ and H/sub 01/ excited with the help of the sequence of stub waveguiding bifurcations located at adjacent waveguide walls is considered. Experiment confirms efficiency of electromagnetic wave interaction
