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…
