Very recently, Sasaki et al. fabricated a microring laser by making the most of the various semiconductor processing methods, and achieved low-threshold laser oscillation [51]. This demonstrates the robustness of thiophene-based oligomers and that these materials are compatible with semiconductor processing. 

The novel electronic and photonic properties of thiophene-based oligomers have been described, using examples of FET device applications and laser characteristics. Thiophene-based oligomers were shown to be one of the most promising materials.
