Abstract
We present the first analysis of the mode structure and thresholds of index-guided ring lasers, and on longitudinal mode discrimination of X -junction-coupled ring lasers. Submilliampere thresholds can be achiev ed with single-lateral-mode ring lasers having small refractive index steps. In addition, strong longitudinal mode discrimination can be obt ained with ring lasers of different cavity lengths coupled via an X ju nction.
