Journal ArticleDOI
Trapping and emission of photons by a single defect in a photonic bandgap structure
TL;DR: In this article, a single defect is created inside a two-dimensional photonic bandgap structure, and photons propagating through a linear waveguide are trapped by the defect, which then emits them to free space.
Journal ArticleDOI
Coherent two-dimensional lasing action in surface-emitting laser with triangular-lattice photonic crystal structure
TL;DR: In this article, a surface-emitting laser with a two-dimensional photonic crystal structure is investigated, where the wavelength of the active layer is designed to match the folded (second-order) Γ point of the Γ−X direction.
Journal ArticleDOI
Polarization Mode Control of Two-Dimensional Photonic Crystal Laser by Unit Cell Structure Design
TL;DR: Polarization mode selection in a two-dimensional (2D) photonic crystal laser is demonstrated by controlling the geometry of the unit cell structure by observing coherent lasing action with a single wavelength and controlled polarization in good agreement with the predicted behavior.
Journal ArticleDOI
Control of light emission by 3D photonic crystal
TL;DR: In this paper, 3D photonic crystals with light-emitters and point-defects are fabricated and investigated, and it is experimentally shown that light emission is suppressed at the complete crystal parts, while cavity modes are successfully observed at the defect parts.
Journal ArticleDOI
Multidirectionally distributed feedback photonic crystal lasers
TL;DR: In this paper, the lasing mode of a 2D photonic crystal laser with in-plane multidirectionally distributed feedback effect is analyzed theoretically and experimentally, and the results indicate that 2D coherent lasing oscillation does not occur due to the multi-directional coupling effect in the 2D photon crystal.
