Extended Data Fig. 4: BSWP steady state spatial profile.
From: From enhanced diffusion to ultrafast ballistic motion of hybrid light–matter excitations
(a) Representative steady state emission profiles (note logarithmic scale) measured at the points A and B indicated in Extended Data Fig. 2c. The black solid lines show the exponential fits to the data. (b) Decay length as a function of photonic weight (blue circles), extracted from the exponential fit to the tails of the steady-state distributions given in Fig. 1c. The red circles and the black solid line show the decay lengths calculated as the inverse of the width in Fourier space, from both experimental reflectivity measurements and transfer-matrix simulations respectively.
