Design of a Modified Coupled Resonators Optical Waveguide Supporting a Frozen Mode
Mohamed Y. Nada, Tarek Mealy, Md Shafiqul Islam +5
We design a three-way silicon optical waveguide with the Bloch dispersion relation supporting a stationary inflection point (SIP). The SIP is a third order exceptional point of deg…
Experimental Measurement of Enhanced Group Delay Silicon Photonic Waveguides Indicative of the Frozen Mode Regime Around the Stationary Inflection Point
Nathaniel Furman, Albert Herrero-Parareda, Anthony Rapp +6
The dispersion engineering of periodic silicon photonic waveguides presents opportunities for significant group delay enhancement compared to uniform waveguides of comparable lengt…
Epitaxial rare-earth doped complex oxide thin films for infrared applications
Mythili Surendran, Joshua Rollag, Christopher E. Stevens +7
Rare earth dopants are one of the most extensively studied optical emission centers for a broad range of applications such as laser optoelectronics, sensing, lighting, and quantum…
Lasing at a Stationary Inflection Point: erratum
Albert Herrero-Parareda, Nathaniel Furman, Tarek Mealy +4
This erratum provides an updated fitting function for the lasing threshold of finite-length cavities operating at a stationary inflection point (SIP) or regular band edge (RBE) res…
Frozen mode in coupled single-mode waveguides with gratings
Albert Herrero-Parareda, Nathaniel Furman, Bradley J. Thompson +3
We present a systematic methodology for designing slow-light photonic integrated circuits with a frozen mode based on a special kind of exceptional point of degeneracy (EPD) of ord…
Frozen Mode Regime in an Optical Waveguide With Distributed Bragg Reflector
Nathaniel Furman, Tarek Mealy, Md Shafiqul Islam +5
We introduce a glide symmetric optical waveguide exhibiting a stationary inflection point (SIP) in the Bloch wavenumber dispersion relation. An SIP is a third order exceptional poi…
Experimental Observation of Strong Coupling Between an Epsilon-Near-Zero Mode in a Deep Subwavelength Nanofilm and a Gap Plasmon Mode
Joshua R. Hendrickson, Shivashankar Vangala, Chandriker K. Dass +6
Strong coupling is a phenomenon which occurs when the interaction between two resonance systems is so strong that the oscillatory energy exchange between them exceeds all dissipati…
Broadband Thermal Imaging using Meta-Optics
Luocheng Huang, Zheyi Han, Anna Wirth-Singh +13
Subwavelength diffractive optics known as meta-optics have demonstrated the potential to significantly miniaturize imaging systems. However, despite impressive demonstrations, most…
Controllable finite ultra-narrow quality-factor peak in a perturbed Dirac-cone band structure of a photonic crystal slab
Alex Y. Song, Akhil Raj Kumar Kalapala, Ricky Gibson +9
We show that by using a perturbed photonic Dirac-cone, one can realize ultra-narrow and finite Q-factor peak in the wavevector space, with both the peak value and the width separat…
Polarization dependent femtosecond laser modification of MBE-grown III-V nanostructures on silicon
Sander R. Zandbergen, Ricky Gibson, Babak Amirsolaimani +4
We report a novel, polarization dependent, femtosecond laser-induced modification of surface nanostructures of indium, gallium, and arsenic grown on silicon via molecular beam epit…
500 W Peak Power Cavity Dumped 2-micron GaSb-Based VECSEL
Jacob Hoehler, Ricky Gibson, Jennifer Reed +1
A single transverse mode high pulse-energy VECSEL was developed. The GaSb based VECSEL emits at a wavelength of 2.04 microns with a peak power exceeding 500W while maintaining good…
