Phase Tunable Spatial Light Modulator

Not Available The primary goal of this Phase I SBIR program is to develop cost effective, high performance 1300nm vertical-cavity surface emitting lasers (VCSELs). These devices can serve as a low cost replacement for edge emitting, or stripe lasers, which are commonly used in military and commercial telecommunications networks. Successful VCSEL devices have been fabricated in the shorter infrared wavelength range (850 and 980 nm); however, operation at longer wavelength from 1.3 ¿ 1.5¿m faces many technological challenges. The proposed VCSEL structure and fabrication process will provide single element and multielement devices which will be suitable for low cost, high volume production. In addition, an active layer design will be incorporated that will allow for better temperature stability for long-wavelength VCSELs. The program technology can be used in military systems for applications such as radar; RF photonics; and battle management, command, control, and communications (BMC3). The 1300nm VCSELs will also facilitate the development of low cost, reliable transmitters for system applications which include local area networks (LANs), wavelength division multiplexing (WDM) and cable television (CATV)
