Research Project of Optical Information Technology at ETL under RWC program is given in detail. In this program, firstly, so called CAD (computer-aided design) system for optical devices will be established for the purpose of acceleration on the development of semiconductor optical devices. Devices developed under the CAD system will be implemented into new types of optical information systems ...

ultra-short pulse is a promising technology for achieving ultra-high data rate transmission which is required to follow the increased demand of data transport over an optical communication system. therefore, the propagation of such type of pulses and the effects that it may suffer during its transmission through an optical waveguide has received a great deal of attention in the recent years. we...

ABSTRACT: In this paper, the thermal characteristics of single and double flow plane solar heaters with radiating working gas were analyzed and compared by numerical analysis for the first time. The laminar mixed convection gas flow in the heaters was numerically simulated by the CFD method using the finite volume technique. The set of governing equations included the conservation of mass, mome...
