  • Semiconductor photonic devices using phase change materials
    Patent number: 10877352
    Abstract: Embodiments include apparatuses, methods, and systems including a semiconductor photonic device having a substrate, a waveguide disposed above the substrate, a phase change layer disposed above the waveguide, and a heater disposed above the phase change layer. The waveguide has a modifiable refractive index based at least in part on a state of a phase change material included in the phase change layer. The phase change material of the phase change layer is in a first state of a set of states, and the waveguide has a first refractive index determined based on the first state of the phase change material. The heater is to generate heat to transform the phase change material to a second state of the set of states, and the waveguide has a second refractive index determined based on the second state of the phase change material. Other embodiments may also be described and claimed.
