Modulation of the WS2-linear Ag grating strong coupling device. a Schematic diagram of WS2-linear Ag grating device. b Electric field distribution of the linear Ag gratings with 400 nm period in TE (i) and TM (ii) mode at 617 nm. c, d Simulated reflection spectra of the linear Ag gratings (c) and monolayer WS2-linear Ag gratings (d) with different periods in TM mode. The relevant experimental data are marked with white open circles. e Reflection spectra of the WS2-linear Ag grating devices in TM mode. f PL spectra of the WS2-linear Ag gratings devices in TE (dotted line) and TM (solid line) mode
