WebMay 13, 2024 · It gets reflected twice from the lower and upper boundaries of the waveguide. Then this reflected wave should have the same phase as the initial wave. We can write this condition mathematically and obtain that propagation constant k z = k 2 − m 2 π 2 d 2, where m is integer, k = 2 π / λ and d is a transverse size of the waveguide. WebJun 25, 2024 · Nonlinear nanostructured surfaces provide a paradigm shift in nonlinear optics with new ways to control and manipulate frequency conversion processes at the nanoscale, also offering novel opportunities for applications in photonics, chemistry, material science, and biosensing.
