Out-of-phase-mode oscillation is suppressed in a nearly resonant array of antiguides by introducing high transverse radiation losses (≈ 150 cm−1) in the interelement regions. Ten-element devices operate in the in-phase array mode, diffraction-limited up to 2.5 × threshold, and with lobe widths of 1.6 × diffraction limit at 4 × threshold (230 mW total power)
