摘要:
In conventional organic EL light-emitting devices, the ITO used for a transparent electrode has a refractive index of about 2.0 larger than the refractive index of 1.5 of a transparent glass substrate. As a result, the mode of most of light traveling from the transparent electrode toward the glass substrate is the transparent electrode guided mode, and no light is emitted from the transparent electrode toward the glass substrate. According to the invention, the light extraction efficiency of conventional light-emitting devices such as organic EL light-emitting devices is improved by using mode conversion means so as to solve the problem that conventional light-emitting devices such as organic EL light-emitting devices have low light extraction efficiencies. A light-emitting device of the invention comprises a light-emitting layer on a substrate and mode conversion means for converting the mode from the guided mode into an emission mode. The mode conversion means is provided in the substrate, in the light-emitting layer, or at the interface between the substrate and the light-emitting layer.

An automatic tool storing mechanism which has a plurality of magazines, a transporting device, and a tool exchanging part. Each magazine holds a number of pots each provided with tools. The transporting device transports tool-mounted pots one by one between the position close to the magazine and the waiting position close to the main spindle. The tool exchanging arm takes out an unused tool from the pot which is waiting at the waiting position and attaches it to the main spindle and also removes the used tool from the main spindle and places it in the pot.

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:
The present invention aims to provide a two-dimensional photonic crystal having an optical resonator, which allows the control of the front/back emission ratio of light. To achieve this object, a refractive index member made of a material having a refractive index different from that of air is mounted on a two-dimensional photonic crystal having a body in which holes are periodically arranged. In this construction, the body and the refractive index member cooperatively function as an optical resonator located at the position where the refractive index member is mounted. The light emitted from this optical resonator is stronger on the side having a higher refractive index, i.e. on the side where the refractive index member is mounted. Accordingly, the light emitted from the side where the refractive index member is mounted is stronger than the light emitted from the other side. The ratio of the emission intensity of the two rays of light and, i.e. the front/back emission ratio, can be controlled by changing the material, shape and/or size of the refractive index member.
摘要:
The present invention intends to provide a two-dimensional photonic crystal having a high level of mechanical strength and functioning as a high-efficiency resonator. The two-dimensional photonic crystal according to the present invention includes a slab layer 31 under which a clad layer 32 is located. In the slab layer 31, areas 35 having a refractive index different from that of the slab layer 31 are cyclically arranged to create a two-dimensional photonic crystal. A portion of the cyclic arrangement of the areas 35 are omitted to form a point-like defect 36. This defect 36 functions as a resonator at which a specific wavelength of light resonates. An air-bridge cavity 37 facing the point-like defect 36 is formed over a predetermined range of the clad layer 32. In this construction, the clad layer 32 supports the slab layer 31 except for the range over which the air-bridge space 37 is formed. Therefore, the two-dimensional photonic crystal has a high level of mechanical strength. The presence of the air-bridge space 37 under the point-like defect 36 makes it easy to confine light at the point-like defect 36 by the difference in the refractive index between the slab layer 31 and the air. Thus, the point-like defect 36 functions as a high-performance resonator.
摘要:
In an in-plane heterostructure photonic crystal in which vacancies 32 are periodically arranged in each of forbidden band zones 301, 302, with different cycle distances, a waveguide 33 is formed passing through all the forbidden band zones and point-like defects 341, 342, . . . are formed in each of the forbidden band zones. Since, of all light propagating through the waveguide from the light introduction/take-out section 36 and having the frequency 52 demultiplexed from the predetermined point-like defect, the wavelength of light passing through the predetermined point-like defect is not included in transmission bands 51 of the waveguide in the adjacent forbidden band zone, so that the light is reflected on the boundaries 351 and 352 between forbidden band zones and introduced into the point-like defect. Thereby, the demultiplexing efficiency of light is improved. The same applies to the multiplexing efficiency.
摘要:
The present invention aims to provide a two-dimensional photonic crystal having an optical resonator, which allows the control of the front/back emission ratio of light. To achieve this object, a refractive index member (13) made of a material having a refractive index different from that of air is mounted on a two-dimensional photonic crystal having a body (11) in which holes (12) are periodically arranged. In this construction, the body (11) and the refractive index member (13) cooperatively function as an optical resonator located at the position where the refractive index member (13) is mounted. The light emitted from this optical resonator is stronger on the side having a higher refractive index, i.e. on the side where the refractive index member is mounted. Accordingly, the light (191) emitted from the side where the refractive index member (13) is mounted is stronger than the light (192) emitted from the other side. The ratio of the emission intensity of the two rays of light (191) and (192), i.e. the front/back emission ratio, can be controlled by changing the material, shape and/or size of the refractive index member.
