Compact optical switch using phase-change material for transparent photonic network
We have fabricated optical switches using Si waveguides and phase-change material. The switch is based on an asymmetric Mach-Zehnder interferometer, and thin film Ge2Sb2Te5 is deposited onto the Si waveguides. We observe the change in transmission spectra of the switch by laser pulse irradiations repeatedly. The phase change of the Ge2Sb2Te5 film with only 1-μm-square is sufficient for π-phase ...
متن کاملModular Multilevel Current Source Inverter Using Two-Switch Basic Units
This article is an introduction of a new topology of current source inverter (CSI) which can be alternatively implemented in low/medium power applications. This configuration is organized from series connected sub-multilevel inverters blocks. The basis of the recommended multilevel topology is the connections of many cell units in a decent scheme with the help of H-bridge inverter. The suggeste...
متن کاملAn all-optical, non-volatile, bidirectional, phase-change meta-switch.
Non-volatile, bidirectional, all-optical switching in a phase-change metamaterial delivers high-contrast transmission and reflection modulation at near- to mid-infrared wavelengths in device structures down to ≈1/27 of a wavelength thick.
متن کاملOff - Peak Cooling Using Phase Change Material
The electric utilities in the United States are faced with continued rapid growth in electrical demand. The traditional response to growth in demand has been the expansion of generating capacity. However , economic, environmental, and scheduling constraints will combine to make adequate expansion difficult, if not impossible, in the 1980's. This thesis examines load management as an alternative...
متن کاملEffect of Using Nano Encapsulated Phase Change Material on Thermal Performance of Micro Heat Sink
The aim of this paper is to enhance thermal performance of a microchannel heat sink by using nanoencapsulated phase change material (NEPCM) slurry as a cooling fluid instead of pure fluid. A threedimensional model of a circular channel using water slurry of NEPCM was developed. The results show a significant reduction in the mean fluid temperature along the channel and heat sink wall temperatu...
