PALM

The purpose of the “Photonic Applications for Spatial Light Modulators” (PALM) project is to develop LCOS (Liquid Crystal on Silicon) cells for the ultraviolet and short-wave infrared band. Based on design optimizations of the LCOS cell, new LC (Liquid Crystal) materials are being further developed. The project is carried out by the project partners Fraunhofer IZM and HOLOEYE Photonics AG.

An important aspect of the project is the development of  a highly reliable LCOS package  with similar or lower manufacturing costs compared to standard packages. The particular challenge is to ensure minimal curvature the cell throughout the entire manufacturing process. Optimizing the thermal conductivity of the materials is a way to increase the performance of the package.

HOLOEYE tasks in the project

In this project, HOLOEYE develops two new, high-performance LCOS SLMS:

  • A SLM for the UV wavelength range, from 350nm to 460nm
  • A SLM for the Wavelength range 1520nm-1620nm

These new SLMs are characterized by a high reflectivity and a high photostability, allowing for higher Laser Induced Damage Thershold (LIDT). These performance are achieved through the use of carefully chosen LC materials and the development of new high-reflectivity Dichroic Mirror Coatings for the SMOC backplane.
