Design of Power-Splitter With Selectable Splitting-Ratio Using Angled and Cascaded MMI-Coupler
Design of Power-Splitter With Selectable Splitting-Ratio Using Angled and Cascaded MMI-Coupler is a scholarly work, published in 2018 in ''IEEE Journal of Quantum Electronics''. The main subjects of the publication include power, optics, materials science, Splitter, optoelectronics, optical fiber, silicon photonics, fiber-optic splitter, Power dividers and directional couplers, and microwave engineering. A concept of power splitter with selectable splitting-ratios is proposed based on two multimode interference (MMI) sections connected by a phase-shifting region, in which phase-matching conditions can be fulfilled by using a simple angled section or alternatively using matched phase-shifters.
