Abstract

... the modes to a central pillar with a diameter ≈3 μm, with reflectivities of as high as 90 ... kA cm using the expression where n is the carrier density per unit area, q is the ... be compared to the threshold gain calculated from laser theory by approximating quasiradial modes as confined ...
