We report a single-loop PLL that operates in a wide-bandwidth, fractional-N mode (with no fractional spur reduction scheme) during transient but in a narrow-bandwidth, integer-N mode during phase lock. This hybrid PLL, as an extension of the conventional fast-lock PLL (that shifts only its bandwidth while retaining the same frequency division mode), simultaneously achieves the fastlock advantag...

Energy stored in a resonant medium may be used to amplify the Cerenkov radiation generated by a small driving bunch. The hybrid eigenmode of the system is a combination of Cerenkov radiation and eigenmode of the resonant medium. In the vicinity of the resonant frequency of the medium and when Cerenkov condition is satisfied, the eigenfrequency has an imaginary part. The latter occurs in a relat...

A hybrid automaton is a mathematical model for hybrid systems, which combines, in a single formalism, automaton transitions for capturing discrete updates with differential constraints for capturing continuous ows. Formal veriication of hybrid au-tomata relies on symbolic xpoint computation procedures that manipulate sets of states. These procedures can be implemented using boolean combinations...

The OBE education model is a kind of “learning output” oriented model. In the construction course “Film and Television Production Technology Art”, concept effectively integrated with hybrid teaching mode. article elaborates this topic from model, effectiveness practice, matters that need attention in practice. After it found can improve quality enhance students’ independent learning ability com...

Hybrid vehicles usually have several braking systems, and braking mode switches are significant events during braking. It is difficult to coordinate torque fluctuations caused by mode switches because the dynamic characteristics of braking systems are different. In this study, a new type of plug-in hybrid vehicle is taken as the research object, and braking mode switches are divided into two ty...

We present the results of a numerical study of active mode locking with hybrid lasers which contain an inhomogeneously broadened laser medium and a homogeneously broadened laser medium. The spectral, pulse, and gain characteristics of actively mode-locked hybrid lasers and the influence of the unsaturated gain, the saturation power, and the homogeneous linewidth on the pulse coherence and bandw...

Enormous attention has been paid to optical microresonators which hold a great promise for microlasers as well as fundamental studies in cavity quantum electrodynamics. Here we demonstrate a three-dimensional (3D) hybrid microresonator combining self-assembled hemispherical structure with a planar reflector. By incorporating dye molecules into the hemisphere, optically pumped lasing phenomenon ...

A hyperplane arrangement is a polyhedral cell complex where the relative position of each cell of the arrangement and the composing hyperplanes are summarized by a sign vector computable in polynomial time. This tool from computational geometry enables the development of a fast and efficient algorithm that translates the composition of hybrid systems into a piecewise affine model. The tool prov...

We present an investigation of passive and hybrid mode-locking in Fabry-Pérot type two-section InAs/InP(100) quantum dot lasers that show dual wavelength operation. Over the whole current and voltage range for mode-locking of these lasers, the optical output spectra show two distinct lobes. The two lobes provide a coherent bandwidth and are verified to lead to two synchronized optical pulses. T...
