摘    要:受抑全反射结构中,反射光束和透射光束的古斯汉欣(Goos-Hanchen)位移同时存在,对称双棱镜结构的受抑全反射古斯汉欣位移通常只有波长量级,在实验中很难测量。计算了在入射角大于棱镜与空气界面的临界角小于棱镜与薄膜界面临界角时,镀有电介质膜的对称双棱镜的受抑全反射过程中入射光束的反射系数和透射系数的复数表达式。利用稳态相位法计算得出透射光束和全反射光束的古斯汉欣位移。结果表明,反射光束和透射光束古斯汉欣位移量相同,与入射角大小、薄膜厚度以及空气层厚度有关。在入射角小于但接近棱镜与薄膜界面的临界角,薄膜厚度和空气层厚度一定时,古斯汉欣位移量共振增强达到波长的数百倍。

关 键 词:物理光学  有限波束  稳态相位法  受抑全反射  共振增强

Abstract:Goos-Hnchen (GH) shifts of reflected and transmitted wave beams in frustrated total reflection structure occur simultaneously. Commonly, GH shift of frustrated-total-reflection in symmetric double-prism configuration is only of the order of the wavelength. It's difficult to measure it in experiment. According to Maxwell equations, the complex expressons of reflection coefficient and transmission coefficient are presented when the incident angle is less than the critical angle of prism-film interface but larger than the critical angle of prism-air interface in the thin-film enhanced frustrated total reflection configuration. The GH shifts of reflected and transmitted wave beams are investigated by stationary-phase approach. The results show that the GH shifts of reflected and transmitted wave beams are equal and can be modulated by changing the incident angle and thickness of thin film and air gap. When the incident angle is less than, but close to the critical angle of prism-film interface, the magnitude of the shifts is enhanced by a factor of 102 with given thickness of thin film and air gap.
Keywords:physical optics  finite-sized light beam  stationary-phase approach  frustrated total reflection  Resonance enhancement
