Abstract

An all-optical arithmetic unit with the help of terahertz-optical-asymmetric-demultiplexer (TOAD)-based tree architecture is proposed. We describe the all-optical arithmetic unit by using a set of all-optical multiplexer, all-optical full-adder, and optical switch. The all-optical arithmetic unit can be used to perform a fast central processor unit using optical hardware components. We have tried to exploit the advantages of both optical tree architecture and TOAD-based switch to design an integrated all-optical circuit that can perform binary addition, addition with carry, subtract with borrow, subtract (2's complement), double, increment, decrement, and transfer operations. OCIS codes: 060.1810, 220.4830, 200.4560, 230.4320, 060.4510.

Abstract

Interferometric devices have drawn a great interest in all-optical signal processing for their high-speed photonic activity. The nonlinear optical loop mirror provides a major support to optical switching based all-optical logic and algebraic operations. The gate based on the terahertz optical asymmetric demultiplexer (TOAD) has added new momentum in this field. Optical tree architecture (OTA) plays a significant role in the optical interconnecting network. We have tried to exploit the advantages of both OTA- and TOAD-based switches. We have proposed a TOAD-based tree architecture, a new and alternative scheme, for integrated all-optical logic and arithmetic operations. OCIS codes: 200.4660, 200.4560, 200.4650, 220.4830, 230.4320, 060.4510.

Abstract

This research study is framed for the purpose of developing suitable parameters for measuring the efficiency and performance of an organisation. Efficiency depends on how much inputs are used i.e. effective utilisation of resources through quality, process and managerial efficiency etc. to achieve the required output with customer's satisfaction with a method i.e. proper controlling and monitoring system. Performance is measured by how much or what percent of target is achieved. To develop the parameters of efficiency & performance, best worldwide practices, available literatures, and research publications are reviewed and verified by various industry experts to understand their views on correct measuring tools and validate these parameters. These parameters would assist the organisation to identify the improvement in the puny areas in the manufacturing & service sectors in process, operations, and supporting functions. There is a calculation procedures developed which would be different and it depends and differs from the manufacturing and services industries. The number of parameters for assessment also varies according to the process and operations of the organisation like automobile, engineering, SMEs, educational institutes, hospitals, power distribution organisation etc. For making the scorecard effective, the organisation would develop specific team for data collection, assessment, and scorecard-based departmental strategy making.

49. Designing of Optimized All-Optical Half Adder Circuit Using Single Quantum-Dot Semiconductor Optical Amplifier Assisted Mach-Zehnder Interferometer.

Author

Gayen, Dilip Kumar and Chattopadhyay, Tanay

Abstract

A new and novel scheme for a high speed all-optical half adder based on single Quantum-dot semiconductor optical amplifier (QD-SOA) assisted Mach-Zehnder interferometer (MZI) is theoretically investigated and discussed. In this proposed scheme, pair of input data streams are simultaneously drive the switch to produce sum and carry. In this new design, only single switch can be utilized to design half adder circuit and no additional input beam is required other than two input signals. This design is simpler, smaller and compact than our previously proposed design refid="ref1"/. The impact of the peak data power as well as of the QD-SOAs current density and maximum modal gain on the ER, Q factor with current densities and electron relaxation times etc are explored and assessed by means of numerical simulations.

50. All-optical adder/subtractor based on terahertz optical asymmetric demultiplexer

Author

Gayen, Dilip Kumar, Pal, Rajat Kumar, and Roy, Jitendra Nath

Abstract

An all-optical adder/subtractor (A/S) unit with the help of terahertz optical asymmetric demultiplexer (TOAD) is proposed. The all-optical A/S unit with a set of all-optical full-adders and optical exclusive-ORs (XORs), can be used to perform a fast central processor unit using optical hardware components. We try to exploit the advantages of TOAD-based optical switch to design an integrated all-optical circuit which can perform binary addition and subtraction. With computer simulation results confirming the described methods, conclusions are given.
