TWO-DIMENSIONAL PHOTONIC CRYSTAL OPTICAL RESONATOR AND OPTICAL REFLECTOR USING INTERFERENCE BETWEEN POINT DEFECTS |
摘要 |
The present invention has been devised to provide a two-dimensional photonic crystal optical resonator and optical reflector having high light-extracting efficiency. This is achieved by the following construction. A two-dimensional photonic crystal consisting of a slab-shaped body 11 is created by periodically arranging areas (or holes) 12 having a refractive index different from that of the body 11. A waveguide 13 is formed by providing a linear zone where no hole 12 is bored. Two acceptor type point defects 14 are formed by enlarging two holes 12 spaced apart from each other by a distance L in the longitudinal direction of the waveguide. In this construction, an appropriate selection of the distance L suppresses the reflection and transmission of light at the point defects 14, allowing an efficient extraction of light resonating at the point defects 14. An appropriate selection of the distance L will increase the reflectivity of light at the point defects 14. This allows the body 11 to be used as an optical resonator for producing a resonance of light between the two point defects 14 or an optical reflector for reflecting light at the two point defects 14. <IMAGE>
