Noise and Crosstalk Analysis of SMZ Switches
نویسنده
چکیده
Ultra-high speed OTDM networks require stable and compact all optical switches for demultiplexing and routing. In this paper we investigate the noise and crosstalk characteristics of all optical symmetric Mach-Zehnder (SMZ) switch using a numerical model. Two effects, the relative intensity noise (RIN) and channel crosstalk (CXT) that degrade the performance of the switch are investigated. Numerical simulation results show that RIN and CXT varies with different SOA length, data pulse width, RMSjitter and the bit rate.

Bit Error Rate Performance of All Optical Router Based on SMZ Switches
In this paper we investigate the noise and crosstalk characteristics of all optical router based on SMZ switch using a numerical model. Two effects, the relative intensity noise (RIN) and channel crosstalk (CXT) that degrade the bit error rate (BER) performance of the router are investigated. Numerical simulation results show that for BER of 10, the sensitivity of the receiver with all-optical ...
متن کاملCrosstalk suppression in an all-optical symmetric Mach-Zehnder (SMZ) switch by using control pulses with unequal powers
Suppression of residual crosstalk is desired in switching a data channel from a multiple-channel frame in optical time division multiplexing (OTDM) network. Using the symmetric MachZehnder (SMZ) switch, it is a possible to obtain the desired data channel with relatively low residual crosstalk induced by the adjacent channels. In this paper we propose a simple and effective method to further sup...
متن کاملHigh-speed All- Optical Time Division Multiplexed Node
In future high-speed self-routing photonic networks based on all-optical time division multiplexing (OTDM) it is highly desirable to carry out packet switching, clock recovery and demultplexing in the optical domain in order to avoid the bottleneck due to the optoelectronics conversion. In this paper we propose a self-routing OTDM node structure composed of an all-optical router and demultiplex...
متن کاملComprehensive Evaluation of Crosstalk and Delay Profiles in VLSI Interconnect Structures with Partially Coupled Lines
In this paper, we present a methodology to explore and evaluate the crosstalk noise and the profile of its variations, and the delay of interconnects through investigation of two groups of interconnect structures in nano scale VLSI circuits. The interconnect structures in the first group are considered to be partially coupled identical lines. In this case, by choosing proper values for differen...
متن کاملCrosstalk Investigation of an All-Optical Serial-to- Parallel Converter Based on the SMZ
In this paper an all-optical serial-to-parallel converter (SPC) based on the symmetric Mach-Zehnder (SMZ) interferometers operating at 80 Gb/s is presented. The proposed SPC is simulated and in particular its crosstalk (CXT) characteristics is investigated for a range of different system parameters such as signal and control pulse powers, delay time between the control pulses, and the main phys...
