In article number 1900159, Li Zhang, Yihao Yang, Mengjia He, Hai‐Xiao Wang, Jian‐Hua Jiang, Hongsheng Chen, and co‐workers experimentally demonstrate topological channel intersections, robust valley transport along sharply‐twisted interfaces, and interfaces decorated with random disorder in substrate‐integrated photonic circuitry. This work opens a door to manipulate photonic valley pseudo‐spins in subwavelength‐thickness substrate‐integrated photonic circuitry with excellent self‐consistent electrical shielding.
