Lasing Mode Control in ZnO Nanowires Coupled to TiO2 Nanopillars
Daniel Repp, Francesco Vitale, Raja Hoffmann +4
Nanowire lasers based on spectrally broad gain materials typically exhibit multimode emission, which limits their utility in applications requiring precisely defined spectral chara…
Optimized near-field optical response via adaptive tip illumination
Tao Chen, Wei Wang, Ziyang Gan +7
The performance of tip-enhanced optical microscopy is often limited by inefficient coupling of the excitation field to the plasmonic tip apex, as well as by thermal drift and optic…
Optical characterization of size- and substrate-dependent performance of ultraviolet hybrid plasmonic nanowire lasers
Francesco Vitale, Stephen A. Church, Daniel Repp +10
Nanowire-based plasmonic lasers are now established as nano-sources of coherent radiation, appearing as suitable candidates for integration into next-generation nanophotonic circui…
Tailoring Nanowire Lasing Modes via Coupling to Metal Gratings
Francesco Vitale, Daniel Repp, Thomas Siefke +4
Tailoring the emission of plasmonic nanowire-based lasers represents one of the major challenges in the field of nanoplasmonics, given the envisaged integration of such devices int…
Lasing modes in ZnO nanowires coupled to planar metals
Daniel Repp, Angela Barreda, Francesco Vitale +4
Semiconductor nanowire lasers can be subject to modifications of their lasing threshold resulting from a variation of their environment. A promising choice is to use metallic subst…
Laser stabilization to a cryogenic fiber ring resonator
Benjamin Merkel, Daniel Repp, Andreas Reiserer
The frequency stability of lasers is limited by thermal noise in state-of-the-art frequency references. Further improvement requires operation at cryogenic temperature. In this con…
