A Wavelength Division Mutiplexed Fiber-Optic Communication System

Abstract

This report summarizes the technology developed by Optical Concepts during BMDO SBIR contract DASG60-94-0022. This material presented here is a condensed version of what is described in greater detail in the 8 quarterly reports submitted during this program. In this program, Optical Concepts has developed a technology for fabricating wave-length-division multiplexed (WDM) arrays of long-wavelength vertical cavity surface-emitting lasers (VCSELs) operating nominally at 1550 cm. Prior to this program, 1550 nm VCSELs operating continous wave (CW) at room temperature had not been demonstrated. Optical Concepts has developed CW 1550 cm VCSELs during this program by integrating them with a 980 nm VCSEL optical pump. This optically pumped structure eliminates the need for dopants in the optical cavity, and reduces device heating, leading to CW operation with extremely low threshold gains. The low threshold gain allows fabrication of WDM arrays with a wide wavelength span.
