Test results of the experiment system shown in Figs. 4(a)–4(c). Transmission, effective phase shift, and group delay with two coupled microspheres, with diameters of two spheres of d1 = 1000 μm and d2 = 800 μm. (d1)–(d4) In drawing near one microsphere to couple to the other, the WGM resonance spectrum is split into two modes.
