Notes: Single-frequency, in-phase mode operation has been obtained from a ten-element antiguided phase-locked array with Talbot-type filters by incorporating a buried distributed feedback grating using a three-step metalorganic chemical vapor deposition process. Stabilized frequency with 25 dB side-mode suppression ratio is achieved to 50 mW pulsed output power. In-phase or a mixture of in-phase and out-of-phase modes are observed in nonresonant (nonoptimized) devices. Means of improving device performance (e.g., use of resonant longitudinally uniform arrays or nearly resonant Talbot-filter arrays without gratings in the filter) are discussed.
