Latest Patents
One of Jeongwon Lee's latest patents is titled "Excitation enhancement and extraction enhancement with photonic crystals." This invention discloses a system designed to stimulate emission from emitters, such as quantum dots or organic molecules, situated on the surface of a photonic crystal. The system includes a laser or other light source that illuminates both the emitter and the photonic crystal, which features an energy band structure exhibiting a Fano resonance. This innovative coupling results in spectral and angular enhancement of the emission, effectively reducing the lasing threshold of the emitter. This advancement allows for more efficient organic light-emitting devices and enhances the sensitivity of molecular sensing applications.
Another notable patent is "Continuous-wave organic dye lasers." This invention describes an organic dye laser that produces a continuous-wave output without any moving parts. The design allows for a stationary pump beam that excites the lasing transition over a time scale longer than the decay lifetimes in the organic dye medium. This method prevents photobleaching, enabling continuous operation and lowering the lasing threshold to just a few Watts per square centimeter. Such advancements facilitate electrical pumping for continuous-wave operation, making this technology highly efficient.
