High-speed binary phase-engraved superpixels improve complex light modulation
Complex light modulation—controlling light's amplitude and phase—is key to many laser applications such as optical tweezers and holographic displays. To achieve such modulation at high speeds, amplitude-based electronic modulators use multi-pixel clusters called 'superpixels'. Now, binary phase-engraved superpixels implemented with a Texas Instruments phase light modulator are reported, showing significant improvements over previous methods. The…
