“…Directional couplers are passive four-port microwave components [1], which are widely used in many microwave and millimeter-wave systems for splitting or combining power with certain ratios and under specific requirements such as frequencies, bandwidth, and structure dimensions [2,3,4,5]. Directional couplers with equal power and 90°phase-shift output ports are called 90°hybrid couplers [1].…”

In this paper, rigorous Mode-Matching Technique (MMT) with Generalized Scattering Matrix Method (GSMM) is used to analyze novel hybrid SIW coupler operating at 26 GHz for 5G applications. The introduced coupler has an equal-amplitude of about -3 dB besides 90-degree at its forward and coupled output ports with more than 4 GHz bandwidth. In addition to rigorous analysis, full-wave CST simulator is used to optimize coupler structure and the results from MMT and CST are compared and discussed. The coupler structure divided into two symmetrical cascaded parts with each part having multi-port bifurcated sections. Due to symmetrical structure, analyzing one half of the coupler with MMT has been sufficient for full analysis.

“…Couplers are important components of photonic circuits. Using magneto-optical materials as constituents of such systems allows one to design non-reciprocal devices, such as nonreciprocal Mach-Zehnder interferometers or nonreciprocal directional isolators [1,2]. In this communication, we discuss the principle and the operating conditions of such an isolator based on two coupled magneto-optical waveguides with opposite directions of magnetization.…”

Scattering parameters of a non-reciprocal magneto-optical integrated coupler used as an isolator

We theoretically investigate a non-reciprocal magneto-optical integrated slab directional coupler. The scattering parameters of the structure are derived in the frame of the Coupled-Mode Theory (CMT). By properly designing the coupler, it is possible to achieve a perfect non-reciprocity (with 100% contrast) between the two directions of propagation. Other operating points can also be defined, especially since modal dispersion in the spectral domain is naturally taken into consideration.
