Robust directional couplers for state manipulation in silicon photonic-integrated circuits

HIGHLIGHTS

• who: Moshe Katzman and colleagues from the (UNIVERSITY) have published the research: Robust Directional Couplers for State Manipulation in Silicon Photonic-Integrated Circuits, in the Journal: (JOURNAL)
• what: The authors demonstrate high-fidelity directional couplers for single-qubit gates in photonic waveguides utilizing a novel scheme of detuning-modulated composite segments. Next, the authors propose a composite-sections coupler design with increased tolerance to real-world geometric fabrication errors. This study shows that the scheme developed for a general quantum system is also applicable to integrated optics.
• how: The approach is based on . . .
