Optical properties of bismuth and gallium substituted thulium iron garnet films

( Cd , Mn ) Te ∕ ( Cd , Zn ) Te quantum well waveguide optical isolator with wide wavelength operational bandwidth

“…Waveguide optical isolators based on oxide films have already been reported. [1][2][3][4][5][6] However, these garnet-film isolators have not been monolithically integrated with semiconductor optoelectronic devices because oxide crystals cannot be grown on semiconductor substrates. To fabricate optical integrated circuits, integrating optical isolators with the circuits is one of the most difficult tasks.…”

Metallic nonlinear magnetooptical nonreciprocal isolator

“…These parameters are ε cl = 3.8, ε xx = 3.9, ε xz = ± 0.08 where (+) for forward propagations and (−) for backward propagations and k = 4.83 m −1 [14].…”

“…(14) which is linear of the propagation constantˇindicates that the solution of equation (12) is different for the forward directionˇ+ from the backward directionˇ−.…”

“…The substrate consists of iron garnet films with dielectric tensor ε s is defined as [14] The magnetization M is adjusted in the substrate plane perpendicular to the field propagation, z-direction. We consider only the TM field {E x , H y , E z }.…”

Complete magneto‐optical TE‐TM mode conversion in Cd1–xMnxTe waveguide for integrated optical isolator

“…The operation of the waveguide optical isolator is based on the Faraday effect exhibited by the magneto-optical materials. In the present optical networks, oxide crystals of yttrium iron garnet such as Y 3 Fe 5 O 12 and (GdBi) 3 Fe 5 O 12 are used as magneto-optical materials for the optical bulk isolators [1,2]. Because most of the active optical elements such as isolators, laser diodes, modulators, optical amplifiers, etc.…”
