24 January 2011 All photonic crystal DFBs for laser arrays
Author Affiliations +
Planar 2D photonic crystals are of tremendous interest for integrated optics applications. In the last years, several possible laser cavities have been proposed in that prospect. In this paper, we review our work on 2D photonic crystal second order DFB lasers. We will show that an affine deformation of the photonic crystal allows the fabrication of closely spaced arrays of high Q DFB lasers. Combining waveguide and photonic crystal affine deformations, we demonstrate arrays of optically pumped single mode DFB lasers with controlled wavelength spacing. Potential extension of this scheme will be discussed, altogether with potential for electrical pumping implementation.
