Theory of mode-coupling in the length-modulated laser

1967 International Electron Devices Meeting, 1967
Laser mode coupling induced by internal time-varying perturbation of the optical cavity has been the object of much interest in recent years. It has been shown also that a laser can be phase locked by moving one of its mirrors at a frequency near the axial made interval.

Concurrent coupling of length scales: Methodology and application

Physical Review B, 1999
A strategic objective of computational materials physics is the accurate description of specific materials on length scales approaching the meso and macroscopic. We report on progress towards this goal by describing a seamless coupling of continuum to statistical to quantum mechanics, involving an algorithm, implemented on a parallel computer, for ...

Ferrite coupled-line circulator with reduced length

IEEE Transactions on Microwave Theory and Techniques, 2005
A method to design a circulator based on a ferrite coupled line (FCL) with reduced length is presented. This is achieved by appropriate matching networks. Using ferrite perturbation theory, we derive closed-form expressions for the required matching impedances and the resulting bandwidth of the matched device. Based on this analysis, a realistic design

Asymptotic and finite-length performance of irregular spatially-coupled codes

2014 IEEE International Black Sea Conference on Communications and Networking (BlackSeaCom), 2014
The newest family of low-density parity-check (LDPC) codes, spatially-coupled (SC) codes, is shown to have several desirable characteristics including low implementation complexity and close-to-optimal performance over a range of channels. Furthermore, because of their ribbon-shaped parity-check matrices, window decoding can be used to decode these ...

Enhancing coupling efficiency and propagating length for surface plasmon polaritons

Applied Optics, 2010
A high coupling efficiency and long propagating length technique is suggested for surface plasmon polaritons (SPPs). An attenuated total reflection (ATR) mode is employed to enhance the coupling efficiency by SPPs resonating with the incident light in the SPP launching zone. In the SPP transmitting zone, a step-metal film is embedded in a dielectric to

Theoretical Analysis of Run Length Distributions for Coupled Motor Proteins

The Journal of Physical Chemistry B, 2019
Motor proteins, also known as biological molecular motors, play important roles in various biological processes. In recent years, properties of single-motor proteins have been intensively investigated using multiple experimental and theoretical tools. However, in real cellular systems biological motors typically function in groups, but the mechanisms ...

Infant head circumference growth is saltatory and coupled to length growth

Early Human Development, 2011
Rapid growth rates of head circumference and body size during infancy have been reported to predict developmental pathologies that emerge during childhood.This study investigated whether growth in head circumference was concordant with growth in body length.Forty infants (16 males) were followed between the ages of 2 days and 21 months for durations ...

Coupled length scales in eroding landscapes

1999
We propose a method to study natural topography by means of local transform. A nonlinear local transform Alc[h(x)] of the elevation field h(x) is used to determine a director field of anisotropy a(x). The director field is directly related to local small-scale channel-like features.
