The wide variety of building blocks and light-matter interaction capabilities involved in modern photonic architectures introduce not only unprecedented opportunities but also challenges on the integration of optical materials and devices at all levels within the systems. Hybrid photonic integration and interfaces enable the combination of different ingredients on a single functional unit as well as enhanced manipulation of light, thereby enabling photonic technologies with extraordinary performance, new functionalities and scalability. This feature issue of Hybrid Integrated Photonic Platforms in Optical Materials Express highlights perspectives and technological advancements in this fast-growing, multidisciplinary area. The feature addresses critical challenges and requirements in a broad range of photonic technologies and covers a wide variety of hybrid and heterogeneous photonic integration and interfacing approaches as well as emerging solutions.
The feature issue contains 9 articles including opinion, review and original research papers by leading researchers in this field. In an invited opinion article, Yoo discusses the recent progress in hybrid integrated photonic platforms and outlines new functionalities introduced to the silicon CMOS photonic platform . Li et al. review silicon integrated light-emitters and photodetectors based on 2D materials and discuss strategies using valley-photonics, hybrid and 3D integrations to achieve energy-efficient and miniaturized on-chip optical communication . Jevtics et al. develop a transfer printing process tailored for dense integration of micro-/nano-photonic devices from different material platforms onto a single photonic integrated circuit chip . Jean et al. further study micro-trench resonators for heterogeneous integration with silicon waveguides and demonstrate high-performance photonic devices using this technique as well as its compatibility with various thin-film materials . Lin et al. develop on-chip integration of mid-infrared interband cascade lasers with high-index-contrast chalcogenide photonics that serve as a highly versatile platform for integration with various optical components . Woska et al. report chip-scale photonic molecules with tunable coupling strength via thermal actuation on a liquid crystal elastomer (LCE) platform, and demonstrate tunable photonic devices based on this approach . Sun et al. investigate temperature and initial polarization dependences of electrooptic properties of barium titanate (BaTiO3) crystal thin films that will potentially benefit high-speed electro-optic devices . Ling et al. present electrically tunable metamaterials using InGaZnO Schottky barrier diodes that enable actively modulated terahertz (THz) waves with enhanced performance and reconfigurability . Finally, Zhu et al. propose a metal-insulator-metal (MIM) waveguide structure configured to excite dual-Fano resonance and leverage the improved sensitivity of the structure for temperature detection of ethanol .
