Coherent Perfect Light for Organic Microdevices
Final Report Abstract
The "Coherent Perfect Light for Organic Microdevices" project is based on several concepts that exploit the coherence degree of freedom to design, fabricate, and optimize various organic thin-film devices. Such devices, which have subwavelength dimensions, allow operation in the coherent regime even when the system is operated below the lasing threshold. Our activities here range from simple distributed Bragg reflectors and planar organic microcavities to quite sophisticated systems of PT-symmetric coupled microresonators. Significant improvements in our expertise and technology for the fabrication of organic photonic and optical microdevices in recent years have greatly stimulated our activities. The ability to control the optical design of these devices with subwavelength precision, coupled with the ability to create special photonic states for interaction, has allowed us to better control light-matter interactions using coherence as a degree of freedom. New phenomena such as coherent perfect absorption and transmission or coherent perfect diffraction have been exploited with this approach. While some aspects of our research have focused on fundamental principles, others have had clear practical applications. In particular, our work on coherent perfect absorption could potentially lead to more efficient light-harvesting devices, while our research on PT-symmetric systems could lead to new types of optical switches and modulators. We believe that our efforts to bridge the gap between fundamental science and practical applications in this project have contributed to innovation in the field of organic photonics.
