We present a high-speed and compact optical phase-shifter using multi-layered GaGeTe hybrid integrated on silicon micro-ring resonator (Si-MRR) structure. Under static DC bias, a blue-shift of wavelength is observed for both the Transverse Electric (TE) and Transverse Magnetic (TM) polarizations corresponding to-1.78 pm/V and - 6.65 pm/V, respectively. The device showed a remarkable tuning speed of 2.1 MHz with low optical insertion losses <0.25 dB. The Pockels effect is expected to dominate the observed phase shift.
