Abstract：

Phase　change　materials　are　widely　used　in　photonic　devices　due　to　their　extremely　large　optical　properties.　Phase　change　optical　switches　use　the　difference　in　refractive　index　between　amorphous　and　crystalline　states　to　achieve　＇on＇and　＇off＇.　In　this　paper,　we　design　a　Si-Sc0.2Sb2Te3　(SST)　hybrid　waveguide　1x1　optical　switch.　The　finite　element　method　was　used　to　optimize　the　structural　parameters　of　the　device　and　the　modal　distribution　of　TE　polarization　was　calculated.　The　transmission　performance　of　the　device　is　simulated　by　the　FDTD　method.　In　this　case,　a　very　compact,　2　µm　long　SST　shows　a　large　extinction　ratio　of　more　than　12　dB　and　over　100　nm　bandwidth　operation.　©　Published　under　licence　by　IOP　Publishing　Ltd.
