Two-Photon Micro-Printed Ag 2 Te Quantum Dots-Polymer Hybrid Photonics: A 2D Thermo-Optic Modulation Platform on Fiber End
Year: 2026
Type: conference-paper
Abstract: Polymer microring resonators are attractive for compact thermo-optic control, but their tuning efficiency and dynamic response are usually limited by inefficient local heat generation. A fiber-end PETA polymer microring modified by Ag2Te quantum dots (QDs) and driven by two-dimensional all-optical pumping is presented. The device is fabricated by two-photon polymerization and functionalized by full QD spray coating. Under x-axis pumping the device reaches -81.7 pm/mW, while x+y cooperative pumping increases the sensitivity to -104 pm/mW. The full-coated device maintains a temperature sensitivity of about -245 pm/°C and operates stably up to 100 kHz, with about 42% lower pump power at 100 kHz than one-dimensional modulation.
