Topologically locked for emission The output power from a laser system can be increased by forming an array of lasers; however, because the individual lasers are independent, the resultant output may not be coherent. Dikopoltsev et al . report on the

Ultrafast Phenomena and Nanophotonics XXV.
Following the ultrafast optical excitation of an inhomogeneously broadened ensemble, the macroscopic optical polarization decays rapidly due to dephasing. This destructive interference is, however, reversible in photon echo experiments. Here, we prop

We present the first experimental demonstration of a topological insulator VCSEL array. Our laser consists of 30 emitters, emitting in a single frequency, displaying interference proving that the emitters act as a single laser.

Microcavity exciton polariton systems can have a wide range of macroscopic quantum effects that may be turned into better photonic technologies. Polariton Bose-Einstein condensation and photon lasing have been widely accepted in the limits of low and

There is a great desire to extend ultrasonic techniques to the imaging and characterization of nanoobjects. This can be achieved by picosecond ultrasonics, where by using ultrafast lasers it is possible to generate and detect acoustic waves with freq

We observe experimentally collective lasing of a topological mode in a vertical-cavity surface-emitting laser (VCSEL) array. The array is comprised of pillar-shaped VCSELs in a crystalline model geometry and is optically pumped.

Topological concepts have been applied to a wide range of fields in order to successfully describe the emergence of robust edge modes that are unaffected by scattering or disorder. In photonics, indications of lasing from topologically protected mode
