Design of cylindrical metal-clad semiconductor nano-lasers is undertaken. Specific attention is given to determining the modal gain in structures supporting TM01 Surface Plasmon Polarition (SPP) modes. For representative structures it is indicated that cavity lengths of order 100 µm enable lasing action. In comparison structures supporting TE01 core-confined modes having cavity lengths of order 10 µm may sustain lasing. The analysis methodology adopted offers means to affect the design of candidate semiconductor lasers for bespoke applications.
Key words: Inner core / lasing / material gain / metal-clad / modal gain / nano-laser / outer core
