During this series of talks, students are invited to learn more about the work done within faculty research groups. Dr. Stephen Eikenberry's Astrophotonics research effort arose from several groups of CREOL researchers and now comprises >30 scientists and research students at UCF. They bring together a broad range of expertise in photonic lanterns, fiber optic and microdevices, optical/infrared imagers and …
CREOL CalendarDuring this series of talks, students are invited to learn more about the work done within faculty research groups. Dr. Peter Delfyett's research group focuses on ultrafast high-power optical pulses from semiconductor diode lasers, for applications in applied photonic networks and laser-induced materials modification.
CREOL CalendarTitle: Long-lived Photons in Forbidden States: the influence of light’s topology on its propagation characteristics Abstract: Since the elucidation of total internal reflection by Colladon, Babinet and Tyndall over 150 years ago, bound states of light have been the primary means to transport light, whether on a chip or in optical fibers. We show that light carrying sufficiently high orbital …
CREOL CalendarTitle: Ultrafast Long Wavelength Lasers: A New Field of OpportunitiesAbstract: Up until two decades ago, laser development was mostly centered in the near-infrared spectral region. While this spectral region is well-suited for a number of applications it is sub-optimum for frequency down-conversion to the mid-IR and THz because of Manley-Rowe limitations and limited availability of suitable nonlinear crystals. Similarly, when …
CREOL CalendarTitle: Algorithm-driven paradigms for freeform photonic metamaterials Abstract: In this talk, I will discuss advances in photonic engineering in which algorithmic approaches to device implementation unlock new functional capabilities. In the first part, I will discuss the utilization of freeform optimization for metamaterials in which non-local, multiple scattering dynamics enable new regimes of device efficiency and multi-functionality. These concepts are versatile and …
CREOL CalendarTitle: Engineering Nanophotonic Interfaces to Control Plasmons and Spins Abstract: Light-matter interactions mediated by photonic quasiparticles play a crucial role in realizing next-generation photonic devices by unlocking phenomena that are not accessible with free-space photons and providing efficient interfaces for quantum systems. In the first part of the presentation, I will present the first experimental demonstration of a mid-infrared light-emitting mechanism originating …
