A multi-layer lateral PCM with N-doped Sb70Te30 was proposed and demonstrated. Both current sweep and pulse mode dynamic resistance test show that multi states exist in the device, which can be used for multi-level data storage. Simulation shows the working mechanism of multi-level and confirms the experiment results. More intermediate states can be realized by increasing the cycles of N-doped Sb70Te30...
This paper describes the design and implementation of a prototype 30kW, 200kHz pulsed power supply. A power density greater than 100W/inch3 is achieved with the converter operating at a high ambient temperature of 65 ??C, by utilizing various technologies on topology, control, devices, passives, and thermal management, which can help reduce the converter size. The experimental results demonstrate...
This study investigates a phase-locked loop (PLL) controlled parallel resonant converter (PRC) for a pulse power capacitor charging application. The dynamic nature of the capacitor charging is such that it causes a shift in the resonant frequency of the PRC. Using the proposed control method, the PRC can be optimized to operate with its maximum power capability and guarantee ZVS operation, even when...
We demonstrate error-free all-optical 40Gb/s wavelength conversion using nonlinear polarisation rotation in semiconductor optical amplifiers (SOAs). The high speed of the device is achieved by incorporating an SOA-based turbo-switch. The switching energy is 10fJ/pulse.
