| Title | TWO-DIMENSIONAL PHOTONIC CRYSTAL WITH AIR BRIDGE STRUCTURE AND MANUFACTURING METHOD FOR THE CRYSTAL |
| Abstract | A two-dimensional photonic crystal, wherein a clad layer (32) is disposed on the lower side of a slab layer (31), and areas (35) having refraction factors different from that of the slab layer (31) are cyclically disposed in the slab layer (31). Also, the crystal comprises a spot defect (36) formed by the missing of a part of the areas (35). The spot defect (36) forms a resonator resonating light of a specified wavelength. An air bridge space (37) is formed in the specified area of the clad layer (32) to face the spot defect (36). Since the slab layer (31) is supported by the clad layer (32) in those areas other than the area in which the air bridge space (37) is formed, the mechanical strength of the two-dimensional photonic crystal is high. Since the air bridge space (37) is present under the spot defect (36), light can be easily entrapped in the spot defect (36) due to a difference in refraction factor between the slab layer (31) and air. Accordingly, the spot defect (36) forms the resonator having high performance. |
