Abstract
An electric field-controlled refractive index tunable device includes a phase change correlated transition metal oxide layer, and E-field responsive charge dopants. The E-field responsive charge dopants either accumulate in the phase change correlated transition metal oxide layer or are depleted from the phase change correlated transition metal oxide layer in response to an E-field applied to the phase change correlated transition metal oxide layer.
