Fig. 1. Experimental setup of switchable spacing MWBFL. (a) Double Brillouin spacing: propagation of injected TLS (thin solid arrow), propagation of first BS (thick solid arrow), propagation of second BS (thick dashed arrow); (b) single Brillouin: propagation of injected TLS (thin solid arrow), propagation of first BS (thick solid arrow), propagation of second BS (thick dashed arrow).
