Vertical-cavity surface-emitting laser operating with photonic crystal seven-point defect structure
نویسندگان
چکیده
A vertical-cavity surface-emitting laser with a two-dimensional photonic crystal ~PC! structure has been investigated for single lateral mode operation. The PC confined mode can be controlled by the lattice constant, the hole diameter, the etching depth, and the defect structure. A seven-point defect structure is proposed to enhance the confinement effect, which is diluted by finite hole depth of the PC structure. We obtained a pure PC confined mode under room-temperature cw conditions with a PC lattice constant of 2 mm, hole diameters of 1.0 and 1.4 mm, and depths of 1.85 and 1.92 mm, respectively. © 2003 American Institute of Physics. @DOI: 10.1063/1.1577835#

Two-Dimensional Photonic Crystal Confined Vertical-Cavity Surface-Emitting Lasers
The two-dimensional photonic crystal (2-D PhC) structure has been investigated as a method for lateral mode control of vertical-cavity surface-emitting lasers (VCSELs). The 2-D PhC structures were designed using an equivalent index model developed for photonic crystal fibers combined with a plane wave expansion method. The etching depth dependence of the PhC structure was incorporated for the f...

Photonic crystal patterns containing two defects were fabricated within a large gain area in vertical cavity surface emitting lasers. By designing effective refractive index changes in the region between the defects through cavity shifts caused by photonic crystals, it was possible to coherently couple laser light output from the defects. This enables a novel way to fabricate coherently coupled...

The control of lateral mode operation using a photonic crystal in a vertical-cavity surface-emitting laser ~VCSEL! is analyzed and confirmed experimentally. By controlling design parameters of the photonic crystal pattern, we have produced photonic crystal VCSELs that operate in higher order defect modes in addition to the fundamental defect mode. The transverse modal behavior is consistent wit...

An approach for creating two-dimensional arrays of coherently coupled vertically emitting laser cavities is demonstrated.
