According to an example embodiment, a filtering-type approach is used with an optical signal conveyed in an optical fiber, such as a multimode fiber (MMF) or a multimode waveguide. Modal dispersion in the optical signal is mitigated.

摘要： We introduce a mechanically tunable photonic crystal structure consisting of coupled photonic crystal slabs. Using both analytic theory, and first-principles finite-difference time-domain simulations, we demonstrate that the transmission and reflection coefficients for light normally incident upon such structures can be highly sensitive to nano-scale variations in the spacing between the slabs. Moreover, by specifically configuring the photonic crystal structures, the high sensitivity can be preserved in spite of significant fabrication-related disorders. We expect such a structure to play important roles in micro-mechanically tunable optical sensors and filters.

摘要： We theoretically introduce a new type of optical all-pass filter based on guided resonance in coupled photonic crystal slabs. The filter exhibits near-complete transmission for both on- and off-resonant frequencies and yet generates large resonant group delay. We further show that such a filter can be mechanically switched into a flat-top band rejection filter. We also show that a single photonic crystal slab can also function either as optical all-pass transmission or flattop reflection filter for normally incident light. Both filter functions are synthesized by designing the spectral properties of guided resonance in the slab. The structure is extremely compact along the vertical direction.
摘要翻译：我们理论上引入了一种基于耦合光子晶体板中的引导谐振的新型光学全通滤波器。滤波器对于开启和关闭谐振频率都表现出近乎完整的传输，并且产生大的谐振群延迟。我们进一步表明，这种滤波器可以机械地切换成平顶带阻滤波器。我们还表明，单个光子晶体板也可以作为普通入射光的光学全透镜或平面反射滤光片。通过设计板坯中引导共振的光谱特性来合成滤波器功能。该结构沿垂直方向非常紧凑。
