Coupling length and coupling loss in AlGaAs photonic crystal waveguides

Journal of Optics (India), 2016
In this work, we present the theoretical simulation results of a two parallel plasmonic waveguides structure with same geometries. There is a low-index semiconductor AlGaAs layer between the GaAs layer and the metal layer. The coupling length and coupling loss are calculated at the telecom wavelength (1550 nm) for different structures by employing the ...

Coupling-length trimming by metal loading in optical coupled-waveguides

Optical and Quantum Electronics, 1981
A simple method for adjusting light coupling between two waveguides is presented. The method involves trimming the interaction length by loading a metal film on to one of the coupled-waveguides. It is effective only for the TM mode, and trimming can be achieved very simply.

A Simplified Coupling Power Model of Single Mode Fiber Fusion at Coupling Length

2009 Third Asia International Conference on Modelling & Simulation, 2009
Fabrications of single mode fiber coupling by heating fibers on a flame are very common and popular. However, controlling the output power of fiber coupling process is neither easy nor similar. Power losses occur at the coupling length due to geometrical change of the fibers after fusion.

Length Analyses of Mammalian G-protein-coupled Receptors

Journal of Theoretical Biology, 2001
G-protein-coupled receptors (GPCRs) play a crucial role in mediating effects of extracellular messengers in a wide variety of biological systems, comprising the largest gene superfamily at least in mammals. Mammalian GPCRs are broadly classified into three families based on pharmacological properties and sequence similarities.

On the performance of fixed-length spatially coupled LDPC code

2016 IEEE International Symposium on Broadband Multimedia Systems and Broadcasting (BMSB), 2016
This paper evaluates the rate loss of fixed-length spatially-coupled low-density parity-check (SC-LDPC) code compared to the asymptotic performance of such code. In previous works, SC-LDPC with sufficient length of codeword shows excellent asymptotic performance and attracts a lot of attentions.

Extended Length Heterobifunctional Coupling Agents for Protein Conjugations

Bioconjugate Chemistry, 1996
A series of extended length heterobifunctional coupling agents is described. The successive aminocaproic acid homologation of succinimidyl 4-(N-maleimidomethyl)cyclohexane-1-carboxylate, a known 9-atom long maleimide active ester linker, yielded 16-, 23-, and 30-atom long maleimide active ester homologues. The performance study of these coupling agents

Multiple coupling length nonlinear directional couplers with variable coupling coefficient

Optics Communications, 2003
Multiple coupling length nonlinear directional couplers (NLDCs) with variable coupling coefficient (VCC) are investigated. As examples, two kinds of VCC NLDCs, exponential and Gaussian VCC NLDCs, are numerically simulated. Both couplers show multiple-switching feature and have eminent digital switching characteristic. In addition, the Gaussian VCC NLDC

Optimum coupling junction and cavity lengths for coupled-cavity semiconductor lasers

Journal of Applied Physics, 1985
In this paper we investigate the dependence of the mode suppression in coupled-cavity semiconductor lasers on coupling junction parameters and cavity lengths. An effective mirror formalism is developed and combined with exact numerical analysis to explore the mode behavior across the entire relative cavity gain operating range of coupled-cavity ...

System Benefits of Coupled-Core Multicore Fibers with Different Coupling Lengths

Conference on Lasers and Electro-Optics, 2018
We study the impact of the linear coupling length and the number of cores on the nonlinear benefit of the coupled-core multicore fiber having up to 19 cores. Coupling lengths as short as a few meters improves transmission.
