RT Conference Proceedings T1 Self-Assembled Conjugated Organic/Polymer Microcavities for Optical Resonators and Lasers A1 Yamamoto, Yohei K1 Polímeros AB Optical microcavities play an important role for the next-generation light technology.Recently, we succeeded in fabricating spherical microcavities from π-conjugatedpolymers (CPs) by simple self-assembly process (Fig. 1).[1] We found that themicrocavities show whispering gallery mode (WGM) resonant photoluminescence(PL) upon focused laser excitation, where PL generated inside the sphere is confinedvia total internal reflection at the polymer/air interface.[2–8] The resonance occurswhen the wavelength of the light is an integer multiple of the circumference of themicrosphere. The CP-based microcavities have benefits to the conventionalmicrocavities in the following points: [1] simple and low-energy fabrication process toobtain well-defined microspheres, [2] the microcavities function as both cavity andemitter, [3] the microcavities have high refractive index and photoabsorptivity, and [4]potent use for electrically-driven WGM and laser oscillation. In this presentation,recent results on the fundamentalsof the self-assembly of the CPs,resonant PL from the CPmicrospheres, intra- andintersphere light energyconversion, and the futureprospects to realize light-,electrically-, and chemically-drivenWGM and lasing will be presented.
