Research results show that the behavior of the AOD strongly depends on the period number m, n, and k, the transmission direction of the AOD is related to the values of m and n, while k affects the transmission contrast of the AOD. It is a significant reference for the design of all-optical signal processing devices. C 2011 Society of Photo-Optical Instrumentation Engineers (SPIE).

A theoretical study of a compact and highly efficient isolator consisting of nonlinear plasma and matching metamaterials

“…The corresponding working input intensity is only 143.18 MW cm −2 . Moreover, compared with the designs in [7,18], a design that incorporates only five layers is indeed more compact and could be constructed through the utilization of already existing fabrication processes [17]. Our proposed design may potentially be robust enough, and could possibly represent an unusual design of EM wave isolators in the future.…”

“…A high transmission level can be reached in the spatial Thue-Morse structure, but relatively speaking it is not compact and is comparatively complicated when the generation number of the Thue-Morse structure is increased [7]. Some proposed structures based on asymmetric wave locations have perfect transmission, but the transmission contrast is lower than 0.70 [18]. Some have good transmission contrast, but with an operational wave intensity of more than 4 GW cm −2 .…”

Weyl semimetal assisted nonreciprocal modification of Flat-top optical pulses via defective photonic band-gap structures

“…Biancalana [4] has theoretically investigated the possibility of realizing a nonlinear all-optical diode by using the unique features of quasi-periodic one-dimensional photonic band-gap (1D PBG) structures. In 2011, an all-optical diode with photonic multilayers based on asymmetric light localization was studied [5]. In reference [6] it has been demonstrated how to achieve reversible non-reciprocal optical response in a photonic crystal (PC) with a pair of defects.…”
