Publication number: 20090153843Abstract: An exemplary refractive-index sensor includes a photonic crystal microcavity structure, a light source, and a detector. The photonic crystal microcavity structure includes a photonic crystal layer having first holes and a second hole defined therein. The first holes are arranged in a regular pattern of staggered parallel rows. The second hole is at an approximate center of the regular pattern, instead of a first hole. A diameter of the second hole is different from that of the first holes. The first holes at each of opposite ends of the row having the second hole are omitted, thereby defining an input waveguide and an output waveguide. The light source is adjacent to the input waveguide. The detector is adjacent to the output waveguide.Type: ApplicationFiled: June 20, 2008Publication date: June 18, 2009Applicants: TSINGHUA UNIVERSITY, HON HAI PRECISION INDUSTRY CO., LTD.Inventors: Xiao-Ling Wang, Guo-Fan Jin, Zhen-Feng Xu, Jun Zhu

Publication number: 20090116033Abstract: An exemplary refractive-index sensor includes a photonic crystal microcavity structure, a light source, and a detector. The photonic crystal microcavity structure includes a photonic crystal layer having first holes and a second hole. The first holes are arranged in a pattern of staggered parallel rows. The second hole is located at an approximate center point of the middle row of the pattern rather than a first hole. A diameter of the second hole is less than that of each of the first holes. Some of the first holes disposed at each of opposite ends of a diagonal row having the second hole are omitted to define an input waveguide and an output waveguide.
