| description | A novel type of strong-index-guided laser structure for achieving coherent, high-power (/spl sim/1 W) reliable operation is proposed, analyzed, and demonstrated for the first time. The three-core antiresonant-reflective-optical waveguide (ARROW) laser combines the relatively large fabrication tolerances of single-core ARROW-type devices with the excellent intermodal-discrimination properties of small-element-number (10) ROW arrays, which are known to have tight fabrication tolerances. For single-spatial-mode selectivity the device relies both on ARROW-type (lateral) reflectors and interelement loss. The effect of interelement loss on the resonant in-phase mode and the unwanted nonresonant modes is calculated, and the results are used to design optimal structures. For structures of index step, /spl Delta/n, of 0.1; element/interelement width ratio of 5; 500 cm/sup -1/ interelement-loss coefficient; and 7.5-/spl mu/m-wide individual elements, intermodal discrimination /spl ges/5 cm/sup -1/ is obtained over a relatively large range in /spl Delta/n: /spl sim/0.01. Above-threshold analysis shows that, due to strong index guiding, the structures are virtually immune to gain spatial hole burning. The central-lobe energy content is 65-70%, and the emitting aperture is 25 /spl mu/m, which should provide 1 W CW reliable single-mode power from devices with oxide-free facets. Preliminary experimental results are obtained from Al-free 0.98-/spl mu/m emitting structures: diffraction-limited beam operation up to 30/spl times/ threshold and 0.55 W peak pulsed output power. Finally it is shown that three-core ARROW devices used as integrated master oscillators (MO's) for flared antiguided master-oscillator power amplifiers (MOPA's), provide uniform MOPA near-field intensity profiles, thus opening the way to achieving 3-5 W CW diffraction-limited power from stable, flared MOPA's.< > |
