A significantly simplified type of antiresonant reflecting optical waveguide (ARROW) laser, which is also immune to gain spatial hole burning, is proposed for achieving high-power, single-spatial-mode operation. Modal calculations, which include two-dimensional analysis, confirm strong intermodal discrimination (12–16 cm−1) between the fundamental and the first-order lateral modes. Above-threshold analysis shows that gain spatial hole burning has a negligible effect on the performance of this new type of ARROW device, which in turn dramatically enhances its single-mode, high-power capability by comparison with the conventional ARROW laser.
