摘要

我们利用直接喷墨打印技术,将支持空间分离的耳语画廊模式的无源楔形有机微盘集成到 SU-8 光子集成电路 (PIC) 中。这种创新方法可以混合多种有机材料,实现微盘折射率的可调性,从而克服了传统光刻技术中单一材料谐振器的局限性。在这项研究中,通过混合超支化聚合物使微盘谐振器的折射率与 SU-8 匹配,并将其水平安装到光波导上,从而实现了微盘与波长为 1550 nm 的 PIC 之间的定向耦合。通过原子力显微镜测量制造结构表面的横截面轮廓,获得了成功耦合的几何条件,从而确定了调整耦合效率的方法。

Inkjet-printed waveguide-coupled passive wedge-shaped microdisk resonator with refractive index tunability
We incorporate a passive wedge-shaped organic microdisk supporting spatially separated whispering gallery modes into an SU-8 photonic integrated circuit (PIC) by using direct inkjet printing. This innovative method allows the mixing of multiple organic materials, enabling tunability of the refractive index of microdisks, thereby overcoming limitations of single-material resonators from conventional lithography. In this study, the microdisk resonator, with a refractive index matching that of SU-8 by mixing hyperbranched polymers, is mounted horizontally to an optical waveguide, achieving directional coupling between the microdisk and PIC at a wavelength of 1550 nm. Geometrical conditions for successful coupling were obtained by measuring the cross-sectional profile of the fabricated structure’s surface via atomic force microscopy, determining ways to adjust the coupling efficiency.

期刊介绍: The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community. Optical Materials Express (OMEx), OSA''s open-access, rapid-review journal, primarily emphasizes advances in both conventional and novel optical materials, their properties, theory and modeling, synthesis and fabrication approaches for optics and photonics; how such materials contribute to novel optical behavior; and how they enable new or improved optical devices. The journal covers a full range of topics, including, but not limited to: Artificially engineered optical structures Biomaterials Optical detector materials Optical storage media Materials for integrated optics Nonlinear optical materials Laser materials Metamaterials Nanomaterials Organics and polymers Soft materials IR materials Materials for fiber optics Hybrid technologies Materials for quantum photonics Optical Materials Express considers original research articles, feature issue contributions, invited reviews, and comments on published articles. The Journal also publishes occasional short, timely opinion articles from experts and thought-leaders in the field on current or emerging topic areas that are generating significant interest.
