Fast Liquid Crystal on Silicon Phase Modulator

Ref No: Yip-3376-16

Researchers in the Department of Engineering have developed a new type of high speed phase modulator based on Liquid Crystal on Silicon (LCoS) technology. This is expected to enable faster optical switches for telecoms applications, higher quality holographic displays and enhanced live cell microscopy.


Key benefits include:

  • Very fast, with around 40 µs switching time
  • 256 greyscale and very good switching depth
  • Polymer free, no grating structure
  • Works with off the shelf liquid crystal, and may be optimised using a proprietary liquid crystal mixtureThe team is now keen to collaborate with suitable partners for development of the technology.
