Products & Technology The Grating Light Valve Technologies Silicon Light Machines has strong optical MEMS technical development capability, holds a broad optical IP portfolio. The patented Grating Light Valve™ (GLV™) technology comprised of a series of microscopic ribbons on the surface of a silicon chip, the GLV device is a diffractive MEMS that acts a dynamic, tunable grating, that can switch, attenuate and modulate laser light with unparalleled precision. Compared to other MEMS, the GLV device offers significant advantages in terms of speed, accuracy, reliability and ease of manufacturing. The technology can widely used in high definition display, directly write to media applications, Maskless lithography and other optical modulation applications.
