Topological Insulator Lasers Invited
01:30-02:00
2017-10-03 01:30 2017-10-03 02:00 America/Denver Topological Insulator Lasers We present the new concept of Topological Insulator Lasers: lasers with cavities acting as superconductors for the light circulating in them. The topologically-protected transport of light in the cavity assures high slope efficiency and single mode lasing even in the presence of defects and disorder.

PT-symmetry breaking of topological edge-states in SSH micro-ring laser arrays
02:00-02:15
2017-10-03 02:00 2017-10-03 02:15 America/Denver PT-symmetry breaking of topological edge-states in SSH micro-ring laser arrays The PT-symmetry breaking for topological edge-states are studied in SSH micro-resonator laser arrays. For edge modes, the PT-symmetry breaking threshold reduces when the coupling strength between closely paired elements is increased. Such topological edge-modes are demonstrated in a 16-ring SSH PT-laser arrangement. Hilton Santa Fe Historic Plaza Salon III

Lasing in Micro- and Nano-lasers Invited
02:15-02:45
2017-10-03 02:15 2017-10-03 02:45 America/Denver Lasing in Micro- and Nano-lasers Micro- or nano-lasers are interesting experimental platforms for studying laser physics. They further question our understanding of lasing action, especially in cases where all emission (spontaneous and stimulated) is channeled into very few cavity modes.

Towards Neuromorphic Photonic Networks with Vertical-Cavity Surface Emitting Lasers
02:45-03:00
2017-10-03 02:45 2017-10-03 03:00 America/Denver Towards Neuromorphic Photonic Networks with Vertical-Cavity Surface Emitting Lasers We demonstrate that VCSELs, like neurons in the brain, can successfully generate and communicate photonic spiking signals upon the arrival of external stimuli, yet at sub-nanosecond speeds (eight orders of magnitude faster). This offers great prospects for ultrafast photonic neuronal networks for non-traditional computing paradigms. Hilton Santa Fe Historic Plaza Salon III
