The article looks at the progress made by the high technology industries in developing free-space optics (FSO). Vendors have tried different approaches ranging from airships acting as wireless access points to mesh radio frequency networks to last-mile links where fibers were not used. The FSO technology relies on rooftop lasers and sensors to deliver high-speed point-to-point links between buildings. The technology is designed to suit carrier-deployed services and enterprise-local area network connections between buildings. LightPointe, the remaining FSO-focused business in the U.S., reported that the funding for the FSO initiatives has increased.

    We obtained the second harmonic of a frequency-tripled Nd:YVO4 laser at wavelength of 177.3 nm with 12.95 mW output by using an optically contacted KBe2BO3F2-CaF2 prism-coupled device with a 2.1 mm thick KBe2BO3F2 crystal, which is to our knowledge the best result at this wavelength.

    The direct influence of the vertical carrier mobility on the frequency response of bilayered organic photodiodes (PDs) is investigated for the first time. With fullerene as the acceptor material, changing vertical hole mobility from 2.3×10-5 to 2.8×10-4 cm2/V s increases PD bandwidth...

    Two- and three-dimensional stability problems for a rectangular plate under uniaxial compression are solved by the mesh method. It is shown that the difference between the critical loads obtained in the three- and two-dimensional problems is not greater than 5% for arbitrary fixation conditions...
