Influence of thickness error on the operation of adjustable magneto-optical isolators

Abstract

We have performed a theoretical study on the case of transmission-type one-dimensional magnetophotonic crystals (MPCs) to establish a practical magneto-optical isolator (MOI) that operates properly even in the presence of construction errors. We have introduced a very thin MPC structure with high transmittance and a large Faraday rotation, with the capability of adjusting to a perfect MOI. A minor thickness error for the individual layers of this MOI may take it from being a perfect MOI; however, its adjustability can provide a stable operation against fabrication errors.

Tunable multifunctional magneto-optical devices based on magnetophotonic crystals comprising liquid crystal defect layers

“…34,35 Particularly, the operational stability is very important for the devices such as optical isolators which operate at certain conditions. 36,37 Once again consider the discussed structure. It was relatively thick and complex.…”

Influence of arrangement order ratio on the magneto-optical properties of one-dimensional microcavity structures

“…Higher FR, which is of interest for use in many magneto-optical devices, such as, isolators, modulators, sensors, and circulators, can be achieved by various methods, such as increasing the thickness of microcavity layer while considering conditions for design wavelength or increasing the number of Bragg reflector layers to provide the strong localization of light at microcavity layer. In the past several years, the magneto-optical properties of 1D-MPCs have been studied extensively [11][12][13][14][15][16][17][18]. Steel and co-workers have proposed multiple resonant microcavity structures to obtain flat-top high-transmittance enhanced FRs [19,20].…”
