A phase change layer is arranged proximate to a waveguide core, and a heater is formed proximate to the phase change layer. The phase change layer is composed of a phase change material having a first state with a first refractive index at a first temperature and a second state with a second refractive index at a second temperature. The heater is configured to selectively transfer heat to the phase change layer for transitioning between the first state and the second state."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical switches and routers operated by phase-changing materials controlled by heaters","description":"Structures for an optical switch, structures for an optical router, and methods of fabricating a structure for an optical switch.
