Abstract
An optical device may include at least one optical fiber, and a phase change material (PCM) layer on the at least one optical fiber. The PCM layer may include GexSey, where x is in a range of 20-40, and y is in a range of 60-80.
Claims20
An optical device comprising:
- at least one optical fiber;
- and
- a phase change material (PCM) layer on a side of the at least one optical fiber, the PCM layer comprising GexSey, where x is in a range of 20-40 and y is in a range of 60-80,
- wherein the at least one optical fiber comprises a plurality of optical fibers laterally joined together to define an optical switching portion;
- and wherein first and second PCM layers are on opposite sides of the optical switching portion so that a phase of the first and second PCM layers determines a latched switch state from among a plurality of latched switch states.
2 more elements
An optical device comprising:
- at least one optical fiber;
- a phase change material (PCM) layer on a side of the at least one optical fiber, the PCM layer comprising GexSey, where x is in a range of 30-40 and y is in a range of 60-70;
- and
- a heat source coupled to the PCM layer to selectively change the phase of the PCM layer,
- wherein the at least one optical fiber comprises a plurality of optical fibers laterally joined together to define an optical switching portion;
- and wherein first and second PCM layers are on opposite sides of the optical switching portion so that a phase of the first and second PCM layers determines a latched switch state from among a plurality of latched switch states.
3 more elements
A method for making an optical device comprising:
