Reducing threshold modulation of epsilon-near-zero via surface lattice resonance
The epsilon-near-zero (ENZ) condition in thin films enhances nonlinear optical effects but typically requires extremely high irradiance levels, limiting practical applications. This study reduces the transmission switching threshold by combining ENZ materials with a surface lattice resonance (SLR) metastructure of plasmonic antennas. Experimental results show at least a 10× reduction in switching threshold. We will highlight trade-offs and opportunities for further improvement towards applications in integrated photonics and terahertz wave generation.
