TERAHERTZ-BAND OPTICAL FILTER, ITS DESIGNING METHOD, AND ITS MANUFACTURING METHOD |
摘要 |
N (N is an integer greater than or equal to 2) multi-cavity layers (51) each having an optical path length of n times »/2 (n is an integer greater than or equal to 1) and made of a low-refractive index medium are arranged. The cavity layers (51) are coupled using a single-layer coupling layer (54) having an optical path length »/4 and made of a high-refractive index medium, thus forming a multi-cavity structure (30). Matching layers (40) each including a high refractive index layer (52) and a low refractive index layer (53) each having an optical path length of »/4 are disposed at either end of the multi-cavity structure (30).
