Abstract
Active photonic lattices (APLs) of large index step ((Delta) n>=0.05 for spatial-mode stability) have been used, as early as 1988, for effective lateral-mode control in large-aperture (>=100micrometers ) high-power coherent devices. Photonic-bandpass (PBP) structures, so called ROW arrays, have allowed stable, near-diffraction-limited beam operation to powers as high as 1.6W CW and 10W peak pulsed. Photonic-bandgap (PBG) structures, so called ARROW lasers, have provided up to 0.5W peak-pulsed stable, single-mode power and hold the potential for 1W CW reliable single-mode operation from apertures ~10micrometers wide. The solution for high efficiency surface emission, from 2nd order DFB/DBR lasers, in an othonormal, single-lobe beam pattern was found in 2000. That opens the way for the realization fo 2-D surface-emitting, 2nd order APLs for the stable generation of watts of CW single-lobe, single-mode power form large 2-D apertures.
