Abstract

All-optical OR logic gate is realized by use of gain saturation and wavelength conversion in the semiconductor optical amplifiers (SOA). It is operated by the nonlinearity of the SOA gain and hence to obtain the sufficient gain saturation of the SOA, pump signals are amplified by an Er-doped fiber amplifier (EDFA) at the input of the SOA. The operation characteristics of all-optical OR logic gate are successfully measured at 2.5 Gbit/s.

선광(all-optical) OR 논리소자가 반도체 광증폭기 (SOA)의 이득포화와 파장변환 특성을 이용하여 구현되었다. 전광(all-optical) OR 논리소자는 이득의 비선형성에 의해 동작되므로 SOA의 이득포화를 충분히 얻기 위해 펌프신호는 SOA의 입력단에서 어븀 첨가 광섬유 증복기(EDFA)에 의해 증폭되었다. 전광 OR논리소자의 동작특성은 2.5 Gbit/s에서 성공적으로 측정되었다.
