Non-volatile compact optical phase shifter based on Ge₂Sb₂Te₅ operating at 2.3 μm

Non-volatile compact optical phase shifter based on Ge₂Sb₂Te₅ operating at 2.3 μm

We investigate an optical phase shifter based on Ge2Sb2Te5 (GST) integrated with a Si waveguide at mid-infrared (MIR) wavelengths. Since the optical absorption of both amorphous and crystalline GST can be reduced at a longer wavelength, we demonstrate that the optical loss of the phase shifter can b...
