High speed photodetector using accelerated particles controlled by light

Abstract

In this paper, we propose a new design device that can be used to solve the performance degradation of a diode due to after-fabrication process problems which involves the silicon bulk defects. The optical tweezer technique has been used to control the movement of electrons, specifically an electron's speed using a PANDA ring. The PANDA microring is a new form of a modified add-drop filter that can be used to improve the switching speed of a diode by using the optical tweezers for trapping electrons' movement from anode contact to cathode contact. The trapping probe can be adjusted to fit for atom size of 200 pm (picometer) to 1.4 nm (nanometer) by controlling the ring parameters. The goal of this paper is to present the use of a PANDA microring for improving photodetector performance which can be used further for many applications. © 2012 World Scientific Publishing Company.
