Fig. 3: Structural dependence of polarization resolved spectra by simulations.
From: Polarized resonant emission of monolayer WS2 coupled with plasmonic sawtooth nanoslit array
a, b Forward transmittance spectra of the nanoslit array on Al2O3 under the TE (top row) and TM (bottom row) polarized light incidence. Structural parameters for three types of sawtooth nanoslit arrays: Black curve Īøā=ā30Ā°, bā=ā118ānm; red curve Īøā=ā45Ā°, bā=ā200ānm; blue curve Īøā=ā55Ā°, bā=ā260ānm. c, d Forward transmittance spectra of the nanoslit array on Al2O3/SiO2. e, f Backward reflectance spectra of the nanoslit array on Al2O3/SiO2/Si.
