Cascaded second-order non-linear optical effects,specifically the phase-shift that a fundamental frequency wave experiences through cascading during second-harmonic generation and the successive down-conversion,are a promising route to all-optical signal processing.
The effects of fiber length, excess loss and output reflectivity on the output characteristics of two cascaded Raman fiber laser, such as output power, slope efficiency, and threshold power were studied on basis of numerical simulations, and the optimized parameters were given.
Research on cascaded multilevel inverter and its application in STATCOM
Because of the broad application of multilevel converters in the high-power area, a cascaded multilevel voltage-source inverter with phase-shifted SPWM (PS-SPWM) switching scheme is proposed as a static synchronous compensator (STATCOM).
Cascaded Design of the State Observer for Nonlinear Systems in the Presence of External Perturbations
It underlies two types of cascaded procedures for designing the state observers in the class of systems with separable motions: (i) with discontinuous controls and (ii) with high-gain feedbacks.
Cascaded thin lightly loaded airfoils vibrating in a subsonic separated flow
Cascade JFET constant current device is of very high dynamic impedance. In this paper, the selection of the operating point has been discussed in detail. The operating point of Q1 transistor depends on electrical and structural parameters of Q1 and Q2 transistors which compose the cascade JFET constant current device.
