From: Subwavelength InSb-based Slot wavguides for THz transport: concept and practical implementations
(a) Cross-section view of proposed slot plasmonic THz waveguide with gain medium introduced in slot region (marked by red dashed line). Net gain (or loss) versus frequency for different material gain for case of (b) h = 15 μm and (c) h = 50 μm. Net gain (or loss) versus temperature for different material gain for case of (d) h = 15 μm and (e) h = 50 μm.
