Dynamic tuning of slow light transmission in manual nanostructure photonic crystal waveguide

Silicon photonics in China

“…H. Y. Dong's group at the Tsinghua University found that zero-dispersion slow light with wide bandwidth can be realised owing to anti-crossing of the incident waveguide mode and the adjustment waveguide mode by introducing an adjustment waveguide besides the incident waveguide [39]. Y. Ji's group at Beijing University of Posts & Telecommunication studied the slow light propagation in the line waveguide with a square lattice of rods in air [40][41][42]. X. Chen's group at the Shanghai Jiao Tong University proposed a novel and compact all-optical device for tunable slow and fast light propagation in parallel coupled structures consisting of two dissimilar optical nanowires [43].…”
