Lasing at a Stationary Inflection Point: erratum

Abstract

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) resonance, clarifying their asymptotic scaling with the number of unit cells of the periodic cavity.

Figures (3)

• Figure 1: Same plot as in Fig. 4 in the original manuscript parareda_lasing_2023, but with the proper fitting function for the SIP lasing threshold, showing the $1/N^3$ asymptotic scaling for the SIP lasing threshold.
• Figure 2: Same plot as in Fig. 7b in the original manuscript parareda_lasing_2023, but with the proper fitting functions for the SIP and RBE, showing the $1/N^3$ asymptotic scaling. The black dashed line shows the magnitude of the threshold difference, $\Delta n_{th}^{\prime\prime} = n_{R,th}^{\prime\prime} - n_{S,th}^{\prime\prime}$.
• Figure 3: Error of the SIP lasing fitting function for large $N$, showing the asymptotic $1/N^3$ trend. The error tends to a small value even when multiplied by $N^3$ to emphasize the trend at large $N$.
