We have experimentally verified the lasing of a quasiscarred resonance mode (QSRM) in a spiral-shaped InGaAsP microcavity laser by pumping the cavity boundary with current injection. To confirm the lasing of a QSRM, a far field pattern is obtained and six laser emission directions are found; one corresponds to the whispering gallery type modes and the other to a QSRM. By observing the spectrum and lasing thresholds, the lasing characteristics of the QSRM are analyzed.

    We prove that polygonal billiards with contracting reflection laws exhibit hyperbolic attractors with countably many ergodic SRB measures. These measures are robust under small perturbations of the reflection law, and the tables for which they exist form a generic set in the space of all convex...
