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…
Array oscillator in coupled waveguides with nonlinear gain and radiation resistances saturating at exceptional point
Alireza Nikzamir, Albert Herrero-Parareda, Nathaniel Furman +3
A periodically loaded waveguide composed of periodic discrete nonlinear gain and radiating elements supports a stable oscillation regime related to the presence of an exceptional p…
