Helium Triaxial Gradiometer

Not Available This Phase I Small Business Innovation Research proposal describes the development of the most viable technology for 1300nm vertical-cavity surface-emitting lasers (VCSELs). The technical approach overcomes the problems encountered by the many other approaches being pursued and published. Futhermore, it will minimize development time and is compatible with commercially available manufacturing systems. Picolight's ongoing progress in longwave VCSEL technology will be leveraged. The Phase I program has the agressive goal to demonstrate and evaluate 2.5GHz modulation in a 1300nm VCSEL. Compatibility with Picolight driver circuitry will also be evaluated. Additionally, designs will be made for mil-spec-compliant, Gigabit-Ethernet-compliant, and reliable VCSELs for datacom in both multi- and single-mode packages. The Phase II program will develop commercial off-the-shelf (COTS) 1300nm VCSELs suitable for shipboard data links over distances at least 1km and at speeds and arrays at least 1x12 in size. The 1300nm VCSEL effort will be a materials development, and will be in concert with synergistic Picolight efforts in VCSEL design, packaging, driver/receiver circuits, and small-form-factor transceivers.
