On-chip optical sources of 3D photonic integration based on active fluorescent polymer waveguide microdisks for light display application

Abstract In this work, on-chip three-dimensional (3D) photonic integrated optical sources based on active fluorescent polymer waveguide microdisks are proposed for light display application. Fluorescent green and red oligomers with high-efficiency photoluminescence doped into epoxy crosslinking SU-8 as the gain medium. The microdisk-based optically pumping designed fabricated using organic functionalized materials by direct UV written process. promising stacking dual-microdisk structures double layers could provide white signal source generated perpendicular to chip, stimulated in chip. approach realize monolithically assembled vertical horizontal bright emitters. threshold power is obtained 50 mW continuous-wave (CW) pumping. average coefficient of a measured fiber coupling 112 dB/W, that 137 respectively. rising falling response time 60 80 µs under modulating pulsed This technique very achieving 3D application, including circuits information encryption.
