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…
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…
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…
Advancements in Degenerate Distributed Feedback Lasing
Albert Herrero-Parareda, Nathaniel Furman, Filippo Capolino
We advance the concept of degenerate distributed feedback (DDFB) lasing in a double grating photonic structure that operates near a degenerate band edge (DBE) to achieve a robust s…
Low-Threshold Lasing with Frozen Mode Regime and Stationary Inflection Point in Three Coupled Waveguide Structure
Kessem Zamir- Abramovich, Nathaniel Furman, Albert Herrero-Parareda +2
The frozen mode regime is a unique slow-light scenario in periodic structures, where the flat-bands (zero group velocity) are associated with the formation of high-order stationary…
