Stability and Interaction Dynamics of Solitons in Spatially Engineered High-Order Nonlinear Media
Dao Quang Anh, Bui Duc Tinh, Doan Quang Tri +5
We study spatial solitons and their interaction dynamics in nonlinear optical media with spatially engineered refractive index and competing cubic-quintic (CQ) nonlinear profiles,…

Re-entrant parity-time phase transitions in locally coupled ring resonators
Nguyen Duc Anh Quan, Le Xuan The Tai, Doan Quang Tri +3
We investigate two parity-time-symmetric ring resonators coupled over a finite angular region described by a super-Gaussian profile. In the linear regime, analytical spectra are ob…
