Titel
Tunable non-pixelated spatial polarization shaping including an integrated optical addressing unit
Abstract
We present a device for tunable spatial polarization shaping, based on a red light photo-addressable cell. Such a cell compartment is based on a bisazobenzene containing photoaligning layer and a rubbed PI aligning and is filled with the LC mixture E5. Switchable spatial addressing patterns are generated by a 200 channel micro optical addressing unit based on a red VCSEL array (l = 650 nm) and diffractive beam shapers.
