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…
Lasing at a Stationary Inflection Point
Albert Herrero-Parareda, Nathaniel Furman, Tarek Mealy +4
The concept of lasers based on the frozen mode regime in active periodic optical waveguides with a 3rd-order exceptional point of degeneracy (EPD) is advanced. The frozen mode regi…
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…
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…
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…
