摘要： A two-dimensional photonic crystal surface-emitting laser having a photonic crystal (20) in which a photonic crystal periodic structure (21) is located in or near an active layer (first medium) (12) which emits light when carriers are injected thereto. The photonic crystal periodic structure (21) comprises a second medium with a refractive index different from that of the active layer scattered in two-dimensional periodic array. The photonic crystal periodic structure is of a square lattice structure or a triangular lattice structure which has translation symmetry but does not have rotation symmetry. Alternatively, the phtonic crystal periodic structure is of a square lattice structure or a rectangular lattice structure which is classified into pl, pm, pg or cm according to the two-dimensional pattern classification method. It is the most desirable that the lattice structure is composed of triangular lattice points.

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.

摘要： An objective of the present invention is to provide a surface emitting laser capable of selectively generating a laser oscillation in the fundamental mode and thereby emitting a single-wavelength laser light. In a surface emitting laser including an active layer and a two-dimensional photonic crystal provided on one side of the active layer, a reflector 45 or 46 is provided at least at a portion of the circumference of the two-dimensional photonic crystal. The reflector has a reflectance distribution in which the reflectance has a maximum value at a position where the amplitude envelope of the fundamental mode of an internal resonance light created within the two-dimensional photonic crystal. This design strengthens the fundamental mode while suppressing the second mode, thus enabling the laser oscillation in the fundamental mode to be selectively obtained, so that a single-wavelength laser light can be emitted.

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).
