摘要：

Photonic building blocks fabricated using two-photon polymerization laser lithography are reported. 3D polymer structures are fabricated using a direct laser writing process with nonlinear two-photon absorption in photosensitive material. The 3D photonic structures include 3D photonic waveguides, Bragg gratings, and resonators. In particular, high-quality spiral and air-bridge waveguides providing 3D light guiding beyond a single plane are demonstrated. Sub-micrometer features as well as unique coupling interfaces with 1.6 dB coupling losses and large 3 dB bandwidth are also demonstrated. Experimental characterization reveals the good transmission performance of the fabricated photonic devices. In addition, the waveguides are demonstrated to support 30 Gb s(-1)NRZ (nonreturn to zero) and 56 Gb s(-1)PAM4 (pulse amplitude modulation 4) high-speed data. Small power penalties of 0.7 dB for NRZ (BER = 10(-12)) and 1.5 dB for PAM4 (BER = 10(-6)) are obtained.
