We present preliminary results of the characterization of the optical response of GeSbTe (GST) thin-films integrated with SiN nanophotonic circuits at telecom wavelengths. Transmission measurements are carried out GST thin-films of varying width deposited on top of ring resonators. The nanophotonics circuits are fabricated and optimized in order to find the best response when GST is placed atop the waveguiding layer. Our results for the absorption/transmission properties at different phase states of GST thin-films paves the way towards a all-photonic non-volatile memories.
