Lasing Threshold Condition for Oblique TE and TM Modes, Spectral Singularities, and Coherent Perfect Absorption
Ali Mostafazadeh, Mustafa Sarisaman
We study spectral singularities and their application in determining the threshold gain coefficient for oblique transverse electric/magnetic (TE/TM) modes of an infinit…

Spectral Singularities in the Surface Modes of a Spherical Gain Medium
Ali Mostafazadeh, Mustafa Sarisaman
We study the surface modes of a homogeneous spherical gain medium and provide a comprehensive analytic treatment of a special class of these modes that support spectral singulariti…

Spectral Singularities and Whispering Gallery Modes of a Cylindrical Gain Medium
Ali Mostafazadeh, Mustafa Sarisaman
Complex scattering potentials can admit scattering states that behave exactly like a zero-width resonance. Their energy is what mathematicians call a spectral singularity. This phe…
