Approaches to Performance Analysis of Packed Switched Optical Ring
نویسنده
چکیده
An optical ring network employing optical packet switching is investigated. An analytical approach allowing the computation of end-to-end cell loss ratio (CLR) is proposed. The CLR dependence on topological parameters (number of stations), network parameters (number of wavelengths), and node structure (buffer capacity) is computed assuming a uniform traffic load. A discrete event simulation confirms the analytical results.

The structure of longitudinal modes of a passively Q-switched, non-planar unidirectional ring-resonator,with Nd:YAG active medium is described in this article. Two different techniques are used to study the longitudinal mode structure of the laser resonator. At first, the fast-fourier transform technique is applied for analyzing the mode beating of the optical fields by intensity frequency str...
متن کاملImproving the Triple Coupled Ring-Resonator Performance as an Optical Filter
In this paper, a three ring-resonator serially coupled is considered as an optical filter. We are going to improve the performance of the designed optical filter by increasing the quality factor and finesse of filtered wavelengths. The first and last rings are coupled to the bus waveguides that carry the input and output fields. The effect of coupling parameters and ring radii on the filtering ...
متن کاملAnalytical Study of Optical Bi-Stability of a Single-Bus Resonator Based on InGaAs Micro-Ring Array
In this paper, for the first time to our knowledge, we investigate the optical bi-stability in a compact parallel array of micro- ring resonators with 5μm radius, induced by optical nonlinearity. Due to the nature of perfect light confinement, resonance and accumulation process in a ring resonator, optical nonlinear effects, even at small optical power of a few milliwatts in this structure are ...

متن کاملPerformance of Optical Burst Switched WDM Ring Network with TTFR System
In this paper, we propose an architecture of Optical Burst Switched WDM ring network. In our proposed OBS ring network, every node is equipped with one tunable transmitter and one fixed-tuned receiver (TTFR) oparating on a given wavelength that identifies the node. TTFR type ring network has an advantage that no receiver collisions occur and each node can detect channel collision by transmitter...
