a Time-dependent trace of normalized optical power transmission from crystalline to amorphous state with the power response down edge in µs level. b The time taken for reaching different levels of extinction ratio is varied as shown in the figure from 0.5 ms to 500 ms. c Simulated pre-programmed voltage pulses are applied for each heater and a two-sided neighbor works simultaneously for GSSe to transient from amorphous to crystalline state
