Paper Abstract

We propose semiconductor-metal subwavelength grating (SMSG) which can be implemented as VCSEL mirror. Such new type of SMSG plays a double role of the electric contact and mirror simultaneously. It facilitates high optical power reflectance, perfectly vertical current injection. Such construction eliminates the inbuilt current confinement and allows scaling of emitted power by simple variation of SMSG spatial dimensions. To give the credibility to proposed design we perform numerical analysis of VCSEL with SMSG using fully vectorial optical model. We discuss properties of the proposed design realized in arsenide-based material configuration.
