α‐Sexithiopene; A new photochromic material for a prototype ultrafast incoherent‐to‐coherent optical converter

Ultrafast incoherent‐to‐coherent optical converters based on α‐ sexithiophen (α‐ 6T ) thin films are described. Unlike state‐of‐the‐art materials for spatial light modulation such as liquied crystals and photorefractives, the spectral concentration and fast response times in α‐6T thin films originate at the molecular level, and thus can be modeled using simple molecular engineering rules.
