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.

We propose a modification of a NALM-based 2R regenerator of phase-encoded signals which operates at considerably lower input powers than was studied earlier. Our modification consists of replacing the core-matched and lossless fiber coupler in the NALM by a coupler with a propagation constant mismatch and loss asymmetrically distributed between the two cores. The performance of the modified reg...

A detailed study of the stability of the soliton states for a nonlinear fiber coupler is presented. It is shown that the stability of the symmetric soliton states is delimited by the point of bifurcation: symmetric states are stable starting from zero energy up to the point of bifurcation, and unstable beyond the point of bifurcation. Asymmetric A-type states are stable at points with positive ...
