Events for the College of Optics & Photonics
Title: Holography in Degraded EnvironmentsAbstract: Environment conditions such as fog, sand, haze, turbid water and turbulence degrade imaging conditions and make it difficult to visual objects in a scene. In this talk, I will describe work at the Naval Research Laboratory to utilize digital holography to operate imaging systems and reconstruct imagery in these challenging environments. Additionally, I will provide …
CREOL CalendarTitle: Extreme Light Control with Metamaterials Abstract: The field of metamaterials, artificial engineered materials, has been rapidly evolving in the past two decades, demonstrating extreme optical phenomena and unprecedented control over wave propagation. In this talk, I discuss recent developments in this field of research, with an emphasis on the role of symmetries in establishing emerging optical responses for metamaterials …
CREOL CalendarOptics Day, an annual event, invites curious minds of all ages and backgrounds to explore the wonders of optics and photonics. It provides an incredible opportunity for the community to become more familiar with CREOL, The College of Optics and Photonics in a relaxed, non-classroom setting. Experience thrilling optical demonstrations in the atrium, where the dynamic Dr. Peter Delfyett will deliver an engaging presentation on …
CREOL CalendarTitle: Ultrafast Nonlinear Nanophotonics: From Superior Components to Advanced Circuits Abstract: Ultrafast sciences and technologies are founded on the principles of ultrashort-pulse nonlinear optics. Until now, their discrete and bulky nature has hindered the utilization of their vast functionalities for many applications, ranging from sensing to computing and quantum information processing. In the past few years, nanophotonic lithium niobate (LN) …
CREOL CalendarTitle: Extreme Space-Time Optics & Quantum Meta-PhotonicsAbstract: We first discuss all-optical modulation with single photons using electron avalanche, resulting in record-high nonlinearities. Then we show that transparent conducting oxides (TCOs) operating in the near-zero index (NZI) regime can provide strong single-cycle modulation, thus enabling novel photonic time crystals. Finally, we discuss scalable quantum photonics with single-photon emitters in silicon nitride …
CREOL CalendarTitle: Advancing Nano- and Quantum Photonics with Machine LearningAbstract: Discovering unconventional optical designs via machine-learning promises to advance on-chip circuitry, imaging, sensing, energy, and quantum information technology. In this talk, we discuss photonic design approaches and emerging material platforms for showcasing machine-learning-assisted topology optimization for optical metasurface designs with applications in thermophotovoltaics, reflective optics, quantum photonic circuitry and lightsail technology. …
CREOL CalendarTitle: Frequency Comb Spectroscopy with Coherent and Incoherent Light Abstract: Optical frequency combs are a unique spectroscopic tool, providing an unparalleled combination of frequency accuracy, high-resolution and broad spectral coverage. In this talk, I will highlight our development of frequency comb spectroscopy techniques that apply to both the active detection of coherent laser light, as well as passive detection of …
