Paper Abstract

This work shows the process of computing coupling coefficients of first-order distributed feedback (DFB) metalsemiconductor quantum-well lasers which emit the violet light for data storage of information technology. The optical waveguide structure for such a laser has semiconductor layers and a built-in metal grating layer. The interface between the metal layer and its neighboring semiconductor layer has a sinusoidal corrugation functioning as the grating. To compute the coupling coefficient of the metal-grating waveguide, a model is constructed by Floquet-Bloch formalism (FB). Ray optics technique (RO) is also used to calculate the coupling coefficients. These two methods have close results.
