Abstract

Coherent laser arrays designed using resonant optical waveguides (ROWs) have proven to offer one of the most promising methods of monolithic beam combining in diode lasers. However, the high lateral transmission that provides strong optical coupling also leads to increased loss - a detriment to laser efficiency and performance. Presented is a derivation of additional design rules to eliminate lateral radiation loss from ROW arrays while still maintaining all the strong coupling properties. Additionally, it is speculated that improved mode discrimination and enhanced field uniformity should result from the proposed design modifications.
