Abstract

This paper numerically investigates, SMI in an oxide aperture VCSEL to optimize the epitaxial structure for higher performance. The standard investigated structure is emitting light at 970 nm from In0.17Ga0.83As-GaAsP QWs sandwiched between 36 pairs of bottom mirror and 23 pairs of top mirror (AlxGa1-xAs). The calculations are based on matrix multiplication for calculating effective reflectivity and transmission with external feedback, combined with a logarithmic gain model and standard laser rate equations. To improve the sensitivity towards self-mixing interference in VCSELs by simple epitaxial means and this should enable us to e.g. measure smaller bending deflections of cantilever sensors
