Abstract

Digital micromirror devices (DMDs) are wavelength and polarization independent, have a faster response rate and are affordable- making it a prime beam shaping tool for the commercial world. However, due to its micro-mirror structure and encoded grating, DMDs diffract and disperse broadband light. Although this dispersion problem has been addressed before, the solutions presented require expensive optics and or precise alignment, making it costly and impractical for commercial use. In this work we propose a simple and easily implementable solution that requires a single lens. We then demonstrate this experimentally by generating broadband modes in the image plane.
