Characterisation a Novel Dual-control Terahertz Optical Asymmetric Demultiplexer Switch
نویسندگان
چکیده
Application of terahertz optical asymmetric demultiplexer (TOAD) in ultrafast all-optical switching has received a great deal of interest in the last few years because of its simplicity and low switching energy [1]. However, existing TOAD switches see Fig. 1(a), suffer from asymmetrical switching window (SW) profile that results in high crosstalk, which in turn affects the bit error rate (BER) performance [1]. In this paper we present a novel method of saturating the semiconductor optical amplifier (SOA) by employing dual-control pulses that results in symmetrical switching window profile, thus reducing crosstalk.

Asymmetric optical loop mirror: analysis of an all-optical switch.
We present an analysis of the optical loop mirror in which a nonlinear optical element is asymmetrically placed in the loop. This analysis provides a general framework for the operation of a recently invented ultrafast all-optical switch known as the terahertz optical asymmetric demultiplexer. We show that a loop with small asymmetry, such as that used in the terahertz optical asymmetric demult...

متن کاملCrosstalk and Noise Characteristics of Non-linear Optical Loop Mirror Demultiplexer and Terahertz Optical Asymmetric Demultiplexer
Crosstalk and noise characteristics of non-linear all optical loop mirror (NOLM) demultiplexer and terahertz optical asymmetric demultiplexer (TOAD) are investigated in this paper. The best demultiplexing conditions are studied in order to minimise the crosstalk and noise, and to achieve reduced power penalty for both all-optical demultiplexing schemes.
