The reliability of electronic device is threatened in high power microwave (HPM) environment. In accordance with the situation that the emulation is ineffective in evaluating the accuracy and precision of the HPM effect to electronic device, the experimental method is used to resolve the problem. Low Noise Amplifier (LNA) and Limiter are selected as the objects for the experiments, the structur...

A simple analysis is presented of twin-stripe semiconductor Y-junction laser amplifier switches that operate through simultaneous changes in gain and refractive index due to free carrier injection. This shows that (in contrast to four-port directional coupler devices based on the same mechnism) good cross-talk performance may be obtained for a wide range of operating conditions.

A novel design of all-optical logic gates based on nonlinear slot waveguide couplers is proposed. NOT, OR, and AND logic gates can be realized by simple single optical directional coupler configuration. Strong polarization dependencies of slot waveguides are effectively utilized for realizing polarization-independent optical directional couplers in linear regime and polarization-dependent all-o...
