Summary: Integrated electro-optic photonic microchip utilizes voltage-controlled Phase-Change Materials to dynamically modulate light beams with low energy consumption. Applying localized electrical pulses alters internal refractive index states instantly without continuous power draw, dramatically cutting thermal dissipation/ power overhead. Direct chip-scale electro-optic beam manipulation furthers: lightweight AR smart glasses, compact near-eye projectors, spatial light modulators.
