Voltage-controlled photonic chip could make smart-glasses displays more efficient

Researchers have demonstrated a photonic chip that steers a laser beam using voltage rather than current. The approach could enable more compact, power-efficient displays for smart glasses by building images point by point instead of using a fixed pixel array.

• The chip steers a laser beam via voltage to form images
• The approach replaces a fixed pixel array with scanning
• Goal is compact, power-efficient smart-glasses displays
