The short-channel effect (SCE) is the main problem of many metal-oxide-semiconductor field-effect transistor (MOSFET) industries. A lot of studies addressing the SCE effect have been conducted. One of the methods used for this is called SOI (silicon-on-insulator) technology. This method has been proven to effectively reduce the SCE effect. In this research paper, the electrical characteristic of an...
This paper highlights the study on various structure of silicon-on-insulator (SOI) optical phase modulators based on free carrier dispersion effect. The proposed modulators employ the forward biased P-I-N diode structure integrated in the waveguide and will be working at 1.55μm optical telecommunications wavelength. Three kinds of structure are compared systematically where the p+ and n+ doping positions...
This paper highlights the study of carrier injection effect on silicon waveguide with p-i-n diode structure integrated on Silicon-on-Insulator (SOI). The device performance is predicted using 2D Silvaco CAD software under different applied voltages at wavelength 1.3 and 1.55 μm. Lπ and VπLπ is minimized at a greater applied voltage. Operating at 1.55 μm is proven to be more efficient in terms of length...

The paper reports on the free carrier absorption loss associated with silicon phase modulator. Two structures are compared: p-i-n and n-p-n structure. The simulations are realized utilizing the 2-D semiconductor simulation package SILVACO. Simulations predict that both structures operate more efficiently at 1.3 μm in terms of free carrier absorption loss. At 1.3 μm, the calculated free carrier absorption...

This paper explains how a Short Message is used as a command to remotely control a switching system. There is a great demand for applications that can remotely control electrical or electronic devices. Over the last decade, the implementation of this concept has been attempted by using the Internet and through power-line modems. However, these solutions are not only complex but also require a physical...

In this paper, we discuss the development of a functioning model for a laboratory inventory management system based on radio frequency identification (RFID) technology. The system allows users to track, search, and label laboratory equipment wirelessly. This system is able to locate inventory and report its status either present or missing. The collected inventory data from RFID is then stored and...
Online signature verification is a process of verifying the writer's identity by using signature verification system. This system can be use as a security system such as verification for assessing entry application and password substitutions. Signature verification technology requires primarily a digitizing tablet and a special pen connected to the universal serial bus port (USB port) of a computer...
