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 a1 in area 31 and a2 in areas 32 and 33, which is smaller than a1. 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： An object of the present invention is to provide a multiplexer/demultiplexer capable of preventing a decrease in multiplexing/demultiplexing efficiency due to an error in wavelength or due to a crosstalk with other wavelengths. A two-dimensional photonic crystal having holes 22 cyclically arranged is provided with an input waveguide 23 and an output waveguide 24. Located between the two waveguides are two point-like defects 25 and 26, each consisting of a region devoid of the holes 22. From the light including various wavelengths and propagating through the input waveguide 23, the two point-like defects extract a ray of light having a wavelength determined by the shape of the point-like defects and introduce it into the output waveguide 24. Compared with the case where there is only one point-like defect, the above-described construction increases the values of the wavelength spectrum of the extracted light at around the resonance wavelength and decreases the values at the wavelength range far from the resonance wavelength. Therefore, the increase in the values of the wavelength spectrum at around the resonance wavelength ensures that the light having the desired wavelength can be extracted from the waveguide by a large amount even if the wavelength of the light propagating through the waveguide is erroneously shifted from the resonance frequency. Occurrence of noises within a wavelength range far from the resonance wavelength and extraction of light having the wavelengths of adjacent channels are also suppressed.

摘要： The present invention provides a two-dimensional photonic crystal in which an absolute photonic band gap (PBG), i.e. a photonic band gap that is effective for both the TE-polarized light and the TM-polarized light within a predetermined wavelength range, is created with an adequate bandwidth. The body 21 is provided with holes 22 arranged in a triangular lattice pattern, where the basic shape of the hole is an equilateral triangle. This shaping and arranging of the holes creates an absolute PBG. Each corner of the equilateral triangle is cut along an arc to leave an adequate distance between the neighboring holes (i.e. an adequate width of the connecting portion of the body). This design makes it possible to enlarge each hole 22 while ensuring an adequate strength of the two-dimensional photonic crystal. This construction creates an absolute PBG having a large width.

摘要： In 2D photonic crystals, cavities having a heightened Q factor are made available, wherein combining the high Q cavities with waveguides affords channel add/drop filters having high resolution.

The point defect (4) contains a plurality of three or more lattice points that neighbor one another, and in these lattice points no low-refractive-index substances (2) are arranged; therein the dimension of the low-refractive-index substance (2) that should be arranged to correspond to at least one of the lattice points nearest the point defect (4) is dimensionally altered from a predetermined dimension.

摘要： The present invention provides a two-dimensional photonic crystal optical resonator and reflector having high light-extracting efficiency. A two-dimensional photonic crystal consisting of a slab-shaped body is created by periodically arranging holes having a refractive index different from that of the body. A waveguide is formed by providing a linear zone where no hole is bored. Two acceptor type point defects are formed by enlarging two holes spaced apart from each other by a distance L in the longitudinal direction of the waveguide. An appropriate selection of the distance L suppresses or increases the reflection and transmission of light at the point defects, allowing an efficient extraction of light resonating at the point defects. This allows the body to be used as an optical resonator for producing a resonance of light between the two point defects or optical reflector for reflecting light at the two point defects.

摘要： The present invention provides an optical multiplexer/demultiplexer that can be smaller in size and higher in Q-factor or efficiency. This object is achieved by the following construction. In a slab-shaped body 11, low refractive index areas 12 having a refractive index lower than that of the material of the body 11 are periodically arranged to construct a two-dimensional photonic crystal, in which a waveguide 13 is formed by not boring holes 12 linearly. A donor type cluster defect 14 is formed by not boring holes 12 at two ore more lattice points located adjacent to the waveguide 13. With this construction, only a specific wavelength of light included in the light propagating through the waveguide 13 resonates at the donor type cluster 14, and the light thus trapped is released to the outside (demultiplexing). Conversely, only a specific wavelength of light may be introduced through the donor type cluster defect 14 into the waveguide 13 (multiplexing).

摘要： A plasma etching method capable of oblique etching with a high aspect ratio and high uniformity is provided. In the plasma etching method, a base body is etched with a high aspect ratio by the following process: An electric-field control device having an ion-introducing orifice penetrating therethrough in a direction inclined from the normal to the surface of a base body is placed on or above the surface of this base body. Plasma is generated on the surface of the base body on or above which the electric-field control is placed. A potential difference is formed between the plasma and the base body so as to attract ions in the plasma toward the base body.
