Optical Signal Time Delay Generation Based on Micro Ring Resonators for Quantum Non Demolition Detection

Abstract Increasing the speed of operation in all optical signal processing is very important. For reaching this goal one needs high speed optical devices. Optical half adders are one of the important building blocks required in optical processing. In this paper an optical half adder was proposed by combining nonlinear photonic crystal ring resonators with optical waveguides. Finite difference time domain method wase used for simulating the final structure. The simulation results confirmed that the rise time for the proposed structure is about 1 ps.

AbstractNonlinear photonic crystal ring resonators are suitable mechanisms that can be used for designing optical logic gates and digital structures. In this paper, we designed two nonlinear resonant rings by adding doped glass rods inside the photonic crystal ring resonator. An optical half adder was designed using these nonlinear photonic crystal ring resonators. We used plane wave expansion and finite difference time domain methods to simulate our optical half adder. The simulations show that when one of the input ports is ON, the normalized optical power at the S is about 90 %. The time delay in this case is 7 ps. Also when both the input ports are ON, the normalized optical power at the C is about 155 %. The time delay in this case is 8 ps.

Obtaining precise and reliable test results requires specific tools on one hand, and at the same time, reliability of the results should not be questioned. One of the necessary steps to achieve this goal is the calibration of the measuring device before the test. This article describes an experiment involving calibration of the device by an independent method called cutting beam calibration carried out on the ultrasonic material tester UMT 01. The standard calibration of this device is carried out by using a dedicated metal disc as a template. Calibration of the tester consisted of determining the time delay of the measured signal. The obtained results were used to prepare charts and to determine of signal time delay, called correction, which also allowed determining the velocity of ultrasonic wave in the tested material in three ways. The experiment was conducted on samples of three species of wood: Norway spruce, Scots pine and sycamore. The velocity of ultrasonic wave from research was compared with literature data.
