摘要： The present invention intends to provide a two-dimensional photonic crystal resonator having a high Q-value. The slab-shaped body 21 is provided with cyclically arranged holes 22. The body 21 is divided into three areas 31-33 with the holes 22 arranged with cycle distances of a 1 in area 31 and a 2 in areas 32 and 33, which is smaller than a 1 . A waveguide 23 passing through the three areas is formed by linearly eliminating the holes 22. The waveguide 23 thus formed can propagate rays of light within a wavelength band that depends on the cycle distance of the holes 22. The cycle distance of the holes in the area 31 differs from that of the areas 32 and 33, and the wavelength band of the light propagating through the waveguide accordingly differs. Therefore, a ray of light whose wavelength is within the waveguide transmission wavelength band of the area 31 but outside of the waveguide transmission wavelength band of the other areas 32 and 33 will be confined within the waveguide of the area 31 and resonate therein. Thus, the waveguide in the area 31 functions as a resonator.
摘要翻译：本发明旨在提供具有高Q值的二维光子晶体谐振器。板状体21设置有周期性布置的孔22.主体21被分成三个区域31-33，其中孔22布置成具有区域31中的循环距离1和区域32和33中的2，小于1。穿过三个区域的波导23通过线性地消除孔22形成。如此形成的波导23可以在取决于孔22的循环距离的波长带内传播光线。孔中的循环距离区域31与区域32和33的区别不同，并且通过波导传播的光的波段相应地不同。因此，其波长在区域31的波导传输波长带内，但在其他区域32和33的波导传输波长带之外的光线将被限制在区域31的波导内并在其中谐振。因此，区域31中的波导用作谐振器。
