Bidirectional ring laser: Stability analysis and time-dependent solutions

Stability and Bifurcation Analysis for a Discrete-time Bidirectional Ring Neural Network Model with Delay

We study a class of discrete-time bidirectional ring neural network model with delay. We discuss the asymptotic stability of the origin and the existence of Neimark-Sacker bifurcations, by analyzing the corresponding characteristic equation. Employing M-matrix theory and the Lyapunov functional method, global asymptotic stability of the origin is derived. Applying the normal form theory and the...

Field Solutions for Bidirectional High-Gain Laser Amplifiers and Oscillators

Graphene-based passively mode-locked bidirectional fiber ring laser.

We present an all-fiber bidirectional passively mode-locked soliton laser with a graphene-based saturable absorber for the first time to the best of our knowledge. Our design includes a four-port circulator to introduce different sections of cavity for the two counter-propagating pulses, so they have distinct output characteristics. Simultaneous bidirectional operation is achieved by appropriat...

Bidirectional Multiwavelength Ring Networks: Performance Analysis and Experimental Studies

High-capacity multiwavelength ring networks with bidirectional WDM add/drop multiplexer (WADM) is analyzed and demonstrated. All channels can be added/ dropped independently in each direction. The capacity of a bidirectional ring is found to be approximately twice that of an unidirectional ring. An eight-wavelength WADM is demonstrated for a data rate of 10 Gb/s per channel, providing an overal...

Performance Analysis of the Bidirectional Ring-Based Multiprocessor

In this paper, we propose and evaluate a bidi-rectional slotted ring architecture for the distributed shared memory multiprocessor model. The performance of the bidirectional ring is compared against the unidirectional ring model using analytical models. The eeects of workload parameters such as miss rate, communication locality and system size on processor utilization and eeective computation ...
