摘要: A surface emitting laser having a laminated structure has a first region and a second region. The first region is a region having at least one guided mode, a propagation mode in which light is propagated in the in-plane direction of a substrate at a laser oscillation wavelength. The second region is a region having a substrate radiation mode in which light is emitted to the side of the substrate at the laser oscillation wavelength.

摘要: Provided is a two-dimensional photonic crystal surface emitting laser that enables easy laser oscillation with two-dimensionally symmetric intensity distribution, using a photonic crystal of a lattice structure having different lengths of primitive translation vectors in plane, realized in a two-dimensional photonic crystal surface emitting laser including an active layer, and a two-dimensional photonic crystal having a two-dimensionally periodic refractive index profile disposed in a vicinity of the active layer. The two-dimensional photonic crystal has a lattice structure where two primitive translation vectors in plane have different lengths, a shape of a member forming lattice points included in a unit cell of the lattice structure has anisotropy with respect to directions of the two primitive translation vectors, and the anisotropy of the shape of the member permits a difference of a coupling coefficient to be smaller than a case where the shape of the member is isotropic.
