摘要

模式分复用（MDM）是一种前景广阔的复用技术，可进一步提高光通信和片上光互连系统的传输容量。此外，多模光开关在 MDM 系统中也非常重要，因为它能直接同时切换多个空间信号，使 MDM 系统更加灵活。在本文中，我们提出了一种基于石墨烯-聚合物混合波导平台的模式无关光开关，它可以在少数模式波导中处理 TE11、TE12、TE21 和 TE22 模式。所提出的开关独立于四种引导模式，优化了聚合物波导中石墨烯电容的埋设位置，以调节石墨烯电容与空间模式之间的共面相互作用。通过改变直波导中石墨烯电容的化学势，可以同时调节 TE11、TE12、TE21 和 TE22 模式。我们提出的开关能使空间模式的独立管理更加灵活高效，在 MDM 传输系统中有着广泛的应用。

Mode-Independent Optical Switch Based on Graphene-Polymer Hybrid Waveguides

Mode-division multiplexing (MDM) is a promising multiplexing technique to further improve the transmission capacity of optical communication and on-chip optical interconnection systems. Furthermore, the multimode optical switch is of great importance in the MDM system, since it makes the MDM system more flexible by directly switching multiple spatial signals simultaneously. In this paper, we proposed a mode-independent optical switch based on the graphene–polymer hybrid waveguide platform that could process the TE11, TE12, TE21 and TE22 modes in a few-mode waveguide. The presented switch is independent of the four guided modes, optimizing the buried position of graphene capacitors in the polymer waveguide to regulate the coplanar interaction between the graphene capacitors and spatial modes. The TE11, TE12, TE21 and TE22 modes can be regulated simultaneously by changing the chemical potential of graphene capacitors in a straight waveguide. Our presented switch can enable the independent management of the spatial modes to be more flexible and efficient and has wide application in the MDM transmission systems.

期刊介绍： Photonics (ISSN 2304-6732) aims at a fast turn around time for peer-reviewing manuscripts and producing accepted articles. The online-only and open access nature of the journal will allow for a speedy and wide circulation of your research as well as review articles. We aim at establishing Photonics as a leading venue for publishing high impact fundamental research but also applications of optics and photonics. The journal particularly welcomes both theoretical (simulation) and experimental research. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files and software regarding the full details of the calculation and experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material.
