Mismatched directional couplers

Optics Letters, 1990
Various twin-core couplers composed of mismatched optical fibers are capable of complete power transfer over lengths only moderately longer than their matched analogs. Examples include tapered and piecewise-continuous mismatched couplers. These linear couplers also provide insight into the mechanism of nonlinear coupling because nonlinearity induces ...

Critical dimensions of directional couplers

2010 IEEE 5th International Conference on Nano/Micro Engineered and Molecular Systems, 2010
The critical dimensions of directional couplers include the waveguide separation at the coupling position, the coupling length, and the bending radius of the waveguides. This paper focuses on discussing the waveguide separation at the coupling position. Two directional couplers have been developed with different waveguide separation.

A GaAs directional coupler

Microwave and Optical Technology Letters, 1990
AbstractThe performance of a monolithic microwave integrated circuit directional coupler fabricated on semi‐insulating GaAs substrate has been presented in this paper. The coupler characteristics were measured to investigate the effect of introducing tapered section terminations at all the ports of the coupler.

Ferrite Directional Couplers

Proceedings of the IRE, 1956
A novel directional X-band coupler based on the nonreciprocal scattering properties of a ferrite cylinder is described. Experimental data for coupling and directivity are given as a function of various parameters. Approximate theoretical expressions for coupling and directivity are derived and discussed.
