Helicene molecules have enormous potential utility. Helicenes are foreseen to act as organic semiconductors, components of fast optical switches, asymmetric catalysts, and molecular actuators. Acene molecules have potential utility as organic semiconductors due to their linear, conjugated pi-electron system. Yet despite this multitude of uses, there has been no method of preparing polymeric hel...

Slowing down or even trapping electromagnetic (EM) waves attract researchers’ attention for its potential applications in energy storage, optical signal processing and nonlinearity enhancement. However, conventional trapping, fact, is not truly because of the existence strong coupling effects reflections. In this paper, a novel metal-semiconductor-semiconductor-metal (MSSM) heterostructure pres...

We discuss how all-optical signal processing might play a role in future all-optical packet switched networks. We introduce a concept of optical packet switches that employ entirely all-optical signal processing technology. The optical packet switch is made out of three functional blocks: the optical header processing block, the optical memory block and the wavelength conversion block. The oper...

This research was to design a 2.4 GHz class E Power Amplifier (PA) for health care, with 0.18um Semiconductor Manufacturing International Corporation CMOS technology by using Cadence software. And also RF switch was designed at cadence software with power Jazz 180nm SOI process. The ultimate goal for such application is to reach high performance and low cost, and between high performance and lo...

For the first time, the feasibility of large port count nanosecond reconfiguration time optical switches is demonstrated using a novel hybrid approach, where Mach-Zehnder interferometric (MZI) switches provide low loss high speed routing with short semiconductor optical amplifiers (SOAs) being integrated to enhance extinction. By repeatedly passing signals through a monolithic hybrid dilated 2...

High voltage multi-gap gas discharge switches are very important tools for pulsed power applications in accelerator laboratories. They have applications for example in driving fast injectionand extraction magnets and beam dumps. Basically, there are two different principles used to realise a high voltage switch. One is based on the use of several semiconductor switches, and the other is based o...

This article discloses part of an invention on plug-and-play converter-level on-state voltage measurement methods for power semiconductor devices. To exclude the external supply required in circuits, a self-power solution is proposed to provide bidirectional low-voltage sources. The application circuit with demonstrated single-switch, single-phase inverter, and three-phase inverter.
