Comparison of Silicon and Chalcogenide-based Chip-scale All-optical 2R Regenerators
An optical, 2R regenerator based on self phase modulation (SPM) spectral broadening, combining a 4 μm wide rib waveguide and a surface relief Bragg grating, both written on a 5 cm-long Si chip is proposed and theoretically ...
Integrated all-optical regenerator on a silicon chip using a phase-shifted Bragg grating as the band pass filter
An optical 2R regenerator based on self phase modulation (SPM) spectral broadening on a 4 μm-wide and 5 cm long silicon (Si) rib waveguide is proposed and theoretically analyzed. The phase- shifted Bragg grating written ...
Design of tunneling field-effect transistor (TFET) with AlGaAs/InGaAs hetero-junction
In this paper a hetero-junction tunnel field effect transistor (HJ-TFET) with the channel length of 20 nm has been introduced and simulated in which the source/channel heterojunction is AlGaAs /InGaAs. With precise selection ...
Analysis and optimization of Tunnel FET with Band gap Engineering
in this paper a high performance double gate tunnel field effect transistor (DG-TFET) is proposed. Band gap engineering is achieved in order to improve the device performance. This novel TFET is formed from variable band ...
