Photonic crystal structures have been used to improve modal properties of broad area semiconductor lasers in recent
years. It has been demonstrated that the width of single-mode semiconductor laser can be increased by at least two
orders of magnitude using the transverse Bragg reflection of two dimensional periodic nanostructures. In this talk, we
will describe a photonic crystal structure to obtain the single mode operation of large-area, edge-emitting semiconductor
lasers. Pulsed and CW operation of electrically pumped, single-mode photonic crystal broad area lasers (100μm wide
and 550μm long) with single-lobe, diffraction-limited far-fields are experimentally demonstrated at room temperature. A
wavelength tuning sensitivity 80 times smaller than a conventional DFB laser is also achieved for the photonic crystal
Bragg laser.
