Comparison of bending losses in integrated optical circuits.

Abstract: We present measured losses in waveguide sections that are caused by connecting two parallel noncollinear straight waveguides and compare the results with theory. Two different offset transitions are considered, one composed of a straight section with sharp corner bends and the other exhibiting a smooth S-shaped transition. These two types of transitions are compared with each other to determine when each has the lowest loss. In general, sharp corner bends are preferred for small offsets, whereas larger offsets exhibit lower loss with the S-bend design. The experimental results were measured for 3-μm-wide Ti-diffused LiNbO3 single-mode waveguides.

Digital quadriphase-shift keying modulator

Abstract: A digital quadriphase-shift keying modulator is described which generates a modulated intermediate carrier frequency (IF) based on a desired number of samples for each input information bit. The design includes a ROM (or RAM) look-up table which stores digitized waveforms. The inphase and quadrature components of a complex baseband signal are translated to an IF at a multiple of the sampling rate simply by alternating the inphase and quadrature samples and alternating signs. The real IF output is produced by summing the inphase and quadrature signals.

Fast neutron detection with silicon carbide semiconductor radiation detectors

Abstract: Silicon carbide (SiC) radiation detectors are being developed for high-temperature applications in harsh radiation environments. Among these applications are characterization of nuclear reactor fuel and detection of concealed fissionable materials, which both require the optimization of SiC fast neutron detectors for detection and quantification of fission neutrons. In order to enhance fast-neutron sensitivity, proton recoil techniques are being used. Fission neutrons were simulated by using a 2.5-MeV deuterium-deuterium (D-D) neutron generator. In order to optimize the neutron detection sensitivity, 2.5-MeV neutron proton-recoil response measurements were made as a function of polyethylene converter layer thickness. Measurements were also made of the sensitivity of the SiC proton recoil detector as a function of angle of incidence of the neutrons. As expected from the angular sensitivity of the detector response, detection of neutrons normally incident to the detector face is favored allowing discrimination of background neutrons and possibly supplying information on the fissionable material location or configuration.
