GaN-based distributed-feedback surface-emitting laser with embedded two-dimensional photonic crystal fabricated by mass-transport technique

Autor: Takeshi Uchida, Katsuyuki Hoshino, Takeshi Kawashima, Aihiko Numata, Yuichiro Hori, Yasuhiro Nagatomo, Shoichi Kawashima, Mamoru Uchida, Hideo Iwase

Publikováno v: 22nd IEEE International Semiconductor Laser Conference.

We report on GaN-based distributed-feedback surface-emitting lasers on a sapphire substrate. Two-dimensional photonic crystal gratings in our device were embedded into GaN-based structures by mass-transport phenomena. We have observed room-temperatur

Publikováno v: Thin Solid Films. 203:113-120

The small angle X-ray diffraction intensity of superlattices (SLs) has been formulated on the basis of a trapeziform composition profile. The analysis using this model enables us to estimate the interface width as well as the layer thicknesses. A GaA
