Pixel-matching optics design and analysis using two Texas Instruments phase light modulators for beam steering in NIR

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

We present an all-reflective optical relay to enhance diffraction efficiency and phase bit depth in free-space optical communication systems using phase light modulators (PLMs) with microelectromechanical system (MEMS) mirror arrays. By combining two Texas Instruments PLMs with a relay mirror system, we created a design that increases phase modulation by a factor of two, allowing for high-efficiency beam steering at near infrared wavelengths. This innovation extends the usable wavelength range beyond the range for which the MEMS PLM is designed and improves diffraction efficiency, particularly for applications at 1550 nm.
