  It was widely accepted that embedding of metallic layers into optoelectronic
structures is detrimental to lasing due absorption in metal. However, recently
macroscopic optical coherence and lasing was observed in microcavities with
intra-cavity single metallic layer. Here we propose the design of the of
microcavity-type structure with two intra-cavity metallic layers which could
serve as contacts for electrical pumping. The design of optical modes based on
utilizing peculiarities of Tamm plasmon provides vanishing absorption due to
fixing of the node of electric field of optical mode to metallic layers.
Proposed design can be used for fabrication of vertical cavity lasers with
intra-cavity metallic contacts.
