“…Here we model a localized PNJ and PH formation in step-index media. We show that despite negligible refractive index contrast between the water ([Formula: see text]) and silica microcylinder (∼1.1), a formation of PNJ and PH is observed with equivalent performance compared to that of silica microcylinder embedded in air ([Formula: see text]). …”
