Document Type and Number:
Japanese Patent JP6973452
Kind Code:
B2
Abstract:
A light emitting device includes resonant parts constituted by a photonic crystal structure, and rows each of which includes the resonant parts arranged along a first direction, wherein light resonating in the resonant part resonates in a first resonant direction and a second resonant direction, the rows are arranged along a second direction, the rows include a first row, and a second row, a distance between the resonant part located furthest at one side of the first direction in the first row and the resonant part located furthest at the one side of the first direction in the second row is different from a distance between the resonant part located furthest at the one side of the first direction and the resonant part located furthest at another side of the first direction in the first row, the first and second resonant directions are along the first and second axes respectively, and in a plan view a length along the first direction of the resonant part and a length along the second direction of the resonant part are equal to each other.
