摘要： A two-dimensional photonic crystal surface emitting laser light source according to the present invention includes a two-dimensional photonic crystal made of a plate-shaped body material provided with a periodic arrangement of identically-shaped holes 242A and an active layer provided on one side of the two-dimensional photonic crystal. The hole 242A is not located on a first half-line 251 extending from the gravity center G1 of the hole in a direction within the plane of the two-dimensional photonic crystal, while the hole 242A is located at least on a portion of a second half-line 252 extending from the gravity center G1 in the direction opposite to the first half-line 251. Injecting electric charges into the active layer generates light, which creates an electric field that encircles the gravity center G1 within the two-dimensional photonic crystal. For a given point on the second half-line 252 at which the hole 242A is located, there is no hole at a point that is symmetrical to the aforementioned point with respect to the gravity center G1, so that there is a difference in the refractive index between the two points. Thus, the electric field vectors at the two points are prevented from canceling each other due to destructive interference, so that the resultant laser light is stronger than conventional examples.

摘要： A laser capable of emitting multiple laser beams is provided. A two-dimensional photonic crystal laser according to the present invention has a laminated structure including an active layer, a first photonic crystal layer having a periodic distribution of refractive index with a first period, and a second photonic crystal layer having a periodic distribution of refractive index with a second period that differs from the first period. This two-dimensional photonic crystal laser can emit a main beam traveling in a direction perpendicular to the two-dimensional photonic crystals and side beams each traveling in a direction inclined with respect to the main beam. These beams can be used, for example, in a recording/reproducing device by means of an optical disk, the main beam being used for recording/reproducing information and the side beams for following up the track.

摘要： A reflection mixing member (13) has an alignment in which light from a first light source is incident on a reflecting surface (13a) and light from a second light source is incident on a reflecting surface (13b). A relationship between a pitch Wp, which is a pitch between portions (triangular prisms) respectively formed of the reflecting surface (13a) and the reflecting surface (13b) in the reflection mixing member (13), and a lens pitch Wf is set to be (Wp/Wf≠1). As a result, light fluxes of respectively different distribution are incident on each lens portion of fly's eye lens 14a, so that it is possible to prevent luminance non-uniformity in light incident on a liquid crystal display panel (5) from being generated and prevent color non-uniformity from being generated on a screen at the same time.

The angle control lens includes a transparent member in a shape of a rotational symmetry, and includes a center convex curved surface area (light-emission area) A1, a peripheral curved surface area (light-emission area) B1, a peripheral curved surface reflection area C1, a center concave curved surface area (light-incidence area) D, and a convex curved surface area E formed between the areas A1, B1. The convex curved surface area E is formed in a position for receiving direct incoming light from the LED (direct incoming light deviated from the center portion), and is optically constructed to anteriorly emit this received light (in a direction intended to be emitted as a result of a light-emission angle being controlled).
