Optical Mode Calculation in Large-Area Photonic Crystal Surface-Emitting Lasers

We discuss algorithms and numerical challenges in constructing and resolving spectral problems for photonic crystal surface-emitting lasers (PCSELs) with photonic crystal layers and large (up to several tens of mm^{2}) emission areas. We show that finite difference schemes created using coarse numer...
