Paper Abstract

This work shows the process of computing coupling coefficients of first-order distributed feedback (DFB) metalsemiconductor quantum-well lasers. InGaAsP/InP/Au lasers with wavelength 1550 nm for optical communications are studied. The optical waveguide structure for such a laser has semiconductor layers and a built-in grating interface between the metal and semiconductor layers. Such interface has sinusoidal corrugation geometry. To compute the coupling coefficient of the metal-grating waveguide, a model is constructed by the Floquet-Bloch method (FB). The Ray-optics method (RO) is also used to calculate the coupling coefficients. These two methods have close results.
