Mismatched directional couplers
Optics Letters, 1990Various 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 ...

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.

Adjustable Directional Couplers
Instruments and Experimental Techniques, 2003The characteristics of directional couplers with coupling factors of 3.0 and 12.6 dB at 1.3 GHz are calculated. The devices are based on 165.1 × 82.5 mm2 rectangular waveguides coupled through their common narrow walls. In both devices, the coupling factor can be varied within ±1 dB relative to its nominal value (at a directivity of no less than 25 dB).

Nonlinear electron-wave directional coupler
Physical Review B, 1996We propose a class of quantum interference device that is an electronic counterpart of the nonlinear optical directional coupler. Nonlinear coupled wave equations including Coulomb charging effects in coupled electron waveguides predict coupling lengths depending on the amplitude of the input electron waves, and also predict that for the initial ...

Efficient photonic crystal directional couplers
Optics Letters, 2003We demonstrate highly efficient and spectrally flat broadband coupling in photonic crystal directional couplers. The result is obtained by use of a novel design with smaller holes between coparallel photonic crystal waveguides for efficient channel-to-channel coupling.

Fiber-optic polarizing directional coupler
Optics Letters, 1984A novel fiber-optic device acting simultaneously as a polarizer and a directional coupler is fabricated by coating a metal layer onto the fused biconical-taper structure of single-mode fibers. This polarizing directional coupler exhibits an extinction ratio of 15 dB together with a 1:1 power-splitting ratio and an excess loss of 2.8 dB.
