Electrically reconfigurable silicon photonic filter enabled by embedded phase change material in microring resonator
Nadir Ali, Rajesh Kumar
We report a tunable optical filter based on phase change material embedded in a silicon microring resonator. The high thermo-optic coefficient of $Ge_{2}Sb_{2}…

Mid-IR non-volatile silicon photonic switches using nanoscale Ge\textsubscript{2}Sb\textsubscript{2}Te\textsubscript{5} embedded in SOI waveguide
Nadir Ali, Rajesh Kumar
We propose and numerically analyze the hybrid Si-Ge\textsubscript{2}Sb\textsubscript{2}Te\textsubscript{5} strip waveguide switches for Mid-IR wavelength of 2.1 m. The switches…

Design of nano-scale high static performance phase-change on-off silicon photonic switch
Nadir Ali, Rajesh Kumar
We report design of a high static performance on-off optical switch using nanoscale phase change material Ge2Sb2Te5 embedded into silicon-on-insulator waveguide. This active materi…
