Light engine design for nonlinear wavemixing AR displays
Light engine design for nonlinear wavemixing AR displays
Nonlinear wavemixing is a novel approach for building augmented reality (AR) displays, offering the potential for bright and immersive experiences. This technology presents unique design considerations due to its use of two synchronized, pulsed infrared laser beams and its sensitivity to light polarization. We present our work on developing light engines for these displays using both LCOS and DLP spatial light modulators. Our work focuses on meeting the distinct challenges of using nanosecond-pulsed IR illumination, from ensuring component compatibility to managing coherent light. We also leverage the polarization-dependent nature of the wavemixing process to reduce component count, paving the way for more compact and efficient AR systems.

Abstract
Nonlinear wavemixing is a novel approach for building augmented reality (AR) displays, offering the potential for bright and immersive experiences. This technology presents unique design considerations due to its use of two synchronized, pulsed infrared laser beams and its sensitivity to light polarization. We present our work on developing light engines for these displays using both LCOS and DLP spatial light modulators. Our work focuses on meeting the distinct challenges of using nanosecond-pulsed IR illumination, from ensuring component compatibility to managing coherent light. We also leverage the polarization-dependent nature of the wavemixing process to reduce component count, paving the way for more compact and efficient AR systems.
