制备了异质外延全石榴石磁光光子晶体（MOPC），用于增强980 nm处的法拉第旋转。MOPC是在Ca，Mg，Zr：Gd 3Ga 5 O 12（111）单晶基片上用射频磁控溅射法生长的Bi 3Fe 5 O 12和Sm 3Ga 5 O 12四分之一波长透明膜交替组成。在共振波长λ =980 nm、比法拉第旋转θ（F）=-7.3度/μ m、吸收系数α =3350 cm（-1）和平行于θ（F）的MO品质因数Q=2平行于α =43.6度处的高MO性能证明了将铋铁石榴石MOPC用于泵浦激光二极管、光放大器、调制器和传感器中的可行性。(C)2007年，美国物理学会。
Heteroepitaxial all-garnet magneto-optical photonic crystal (MOPC) was fabricated to enhance Faraday rotation at 980 nm. MOPC was composed of alternating MO-active Bi3Fe5O12 and transparent Sm3Ga5O12 quarter-wavelength layers grown by rf-magnetron sputtering on Ca,Mg,Zr:Gd3Ga5O12(111) single crystal substrate. High MO performance at the resonance wavelength lambda=980 nm, specific Faraday rotation theta(F)=-7.3 degrees/mu m, absorption coefficient alpha=3350 cm(-1), and MO figure of merit Q=2 parallel to theta(F)parallel to/alpha=43.6 degrees demonstrates feasibility to use bismuth iron garnet MOPCs for application in pump laser diodes, optical amplifiers, modulators, and sensors.
