New Architecture of Interconnect for High-Speed Optical Computerized Data Networks (Nonlinear Response)

Abstract

In the present paper, architecture of optical interconnect is built up on the bases of four Vertical-Cavity Surface-Emitting Laser Diodes(VCSELD) and two optical links where thermal effects of both diodes and links are included. Nonlinear relations are correlated to investigate the power-current and the voltage-current dependences. The good performance (high speed) of the interconnect is deeply and parametrically investigated under wide ranges of the affecting parameters. The high speed performance is processed through three different effects, namely the device 3-dB bandwidth, the link dispersion characteristics, and the transmitted bit rate (soliton). Eight combinations are investigated, each possesses its own characteristics. The best architecture is the one composed of a VCSELD that operates at 850 nm and the silica fiber whatever the operating set of causes. This combination possesses the largest device 3-dB bandwidth, the largest link bandwidth and the largest soliton transmitted bit rate. The increase of the ambient temperature reduces the high-speed performance of the interconnect.
