This Phase I Small Business Innovation Research proposal describes a means to develop a new epitaxial growth technique which as far-reaching use for increasing semiconductor laser performances in terms of power, temperature stability, and emission wavelength. The technique is most beneficial to semiconductors lasers, both edge-emitters and vertical-cavity surface emitting lasers (VCSELs), but it a ...

Multispectral imaging has become a valuable tool in tactical imaging scenarios due to the ability to expose camouflage, identify airborne toxins and fuel plumes, and the ability to provide night vision through the use of infrared imaging. Micro-bolometer arrays work well in these situations by creating a single sensor which is sensitive from the visible to long wave IR imaging regions. The microbo ...

Performance of US students in mathematics and physics has been limited, partly because the traditional pedagogy relies on logical and linguistic methods of teaching, and students are primarily assessed on fact knowledge and discrete skills. Recent achievements in computer science provide revolutionary means for educational reform. Thus, use of the World Wide Web and Java - a package of a new obj ...

Recent progress in self-mixing Doppler sensors have proven that measurement performance similar to that obtained with continuous-wave coherent laser radar is feasible, but with at least an order of magnitude less complexity and cost. We believe that extremely simple hardware signal processors can also be built as single chips, or at most a few chips. This points to the possibility of developing hi ...

This Phase I Small Business Innovation Research describes a means to develop a misalignment-tolerant fiber-optic laser transmitter. The insensitivity to misalignment within the transmitter optical subassembly (OSA) enables passive alignment to single-mode fibers for extremely low-cost, high-performance applications such as fiber-to-the-desk (FTTD) and network access modules. The OSA is based on ...

High-density reconfigurable optical routing interconnect is introduced in this SBIR program for optical signal processing. This structure is based on three key features: 1) Polarization manipulation using 2-D spatial light modulators; 2) polarization complementary geometry; and 3) the throw-away undesired optical energies design. The polarization manipulation provides the basis for "no-moving" par ...

This Small Business Innovation Research Phase I program will determine the practicality of increasing the second harmonic (SH) output of frequency doubling devices by at least 5 times current gutput powers. Altos has demonstrated in preliminary experiments have a 2 times to 3 times increase in SH output by creating thermal gradients across the waveguide structures used to frequency double the lase ...

We propose exploratory development of new epitaxial growth technologies for low-defect GiN epitaxial structures and surrogate substrates. A significant feature of our approach is epitaxial latval overgrowth for "defect filtering." We present arguments that such epitaxial lateral overgrowth will lead to GaN material of unprecedented quality with respect to defects, stress, and purity. In the Phase ...
