Fig. 3From: Ultrafast modulation of valley dynamics in multiple WS2 − Ag gratings strong coupling systemLinear polarized TA spectra of the WS2-linear Ag grating devices. a Linear polarized TA spectra of the WS2-linear Ag grating devices probe in TM mode with different periods. b, c Evolution of linear polarized TA spectra at different delay times (0.24 ps, 2 ps, 10 ps, 30 ps) probed in TE (black line) and TM (red line) mode with a period of 400 nm (b) and 425 nm (c). The excitation wavelength is 560 nmBack to article page
