High tilt angle FLC SLM for optical interconnects

The use of high tilt angle FLC SLM for optical interconnects was discussed. The transmissive SLM was designed as a 320×1 pixels glass SLM with 20 μm pitch pixels and 2 μm pixel deadspace. The SLM was fabricated using standard class 100 cleanroom facilities to make a glass on glass 1D SLM. The results show that a N×N optical switch can be built using the two-hologram architecture.
