“…This is achieved by introducing a set of semiconducting nanowires on a Si waveguide in order to provide a periodic perturbation leading to the controlled rotation of the polarization. Additionally, the number and distance between nanowires has been observed to have a profound effect on the rotation effect, leading to the possibility to tune device operation in order to implement arbitrary polarization rotations, an essential feature needed for the operation of photonic circuits [13,102]. Furthermore, other requirements of photonic devices have been fulfilled thanks to the integration of high-aspect-ratio nanostructures on silicon photonic platforms, including mode filtering achieved with the integration of graphene nanoribbons and featuring TE 1 mode pass filtering with a TE 1 -to-TE 0 extinction ratio of 9.19 dB [103] and wavelength filtering employing silicon-on-insulator nanowires [104], enabling wavelength conversion up to 160 Gb/s with minimal power loss (<3 dB).…”

Integrated photonic platforms have rapidly emerged as highly promising and extensively investigated systems for advancing classical and quantum information technologies, since their ability to seamlessly integrate photonic components within the telecommunication band with existing silicon-based industrial processes offers significant advantages. However, despite this integration facilitating the development of novel devices, fostering fast and reliable communication protocols and the manipulation of quantum information, traditional integrated silicon photonics faces inherent physical limitations that necessitate a challenging trade-off between device efficiency and spatial footprint. To address this issue, researchers are focusing on the integration of nanoscale materials into photonic platforms, offering a novel approach to enhance device performance while reducing spatial requirements. These developments are of paramount importance in both classical and quantum information technologies, potentially revolutionizing the industry. In this review, we explore the latest endeavors in hybrid photonic platforms leveraging the combination of integrated silicon photonic platforms and nanoscale materials, allowing for the unlocking of increased device efficiency and compact form factors. Finally, we provide insights into future developments and the evolving landscape of hybrid integrated photonic nanomaterial platforms.

“…However, the fabrication tolerance was very small with high sensitivity to small fabrication errors. In addition, PRs based on directional coupling (10), (11) have been reported. Soudi et al (11) have proposed a design of directional coupling based PR that contains two simple silicon nanowires with unequal widths.…”

A compact polarization rotator (PR) based on silicon on insulator (SOI) platform with nematic liquid crystal (NLC) is introduced. The NLCs are anisotropic materials which can be used to improve the modal hybridness of the hybrid modes. As a result, a polarization rotation can be achieved over a short propagation distance. The proposed PR is analyzed using the full-vectorial finite-difference method and the full-vectorial finite-difference beam propagation method. The numerical results reveal that at the operating wavelength of 1.55 μm, the PR has a compact device length of 11.67 μm with 15.5 dB extinction ratio (ER) for both polarization conversions. The insertion losses of the reported PR are equal to 0.29 dB and 0.59 dB for TE to TM and for TM to TE conversions, respectively. Moreover, it offers a broad bandwidth of (860 -1780 nm) for TE to TM and (890 -1790 nm) for TM to TE with an ER better than 10 dB. The fabrication tolerances and influences on the performance of the PR for the different structure geometrical parameters and operating wavelength are also investigated.

“…However, a silicon waveguide is naturally polarization dependent due to the structural birefringence [3,4]. To circumvent this issue, a polarization beam splitter (PBS) and rotator are generally utilized to build a polarization-independent circuit [5,6]. A PBS is of considerable importance in the polarization-diversity system, which aims to split two orthogonal quasi-transverse-electric (TE) and quasi-transversemagnetic (TM) polarizations into two individual channels, respectively.…”

A compact and fabrication-tolerant polarization beam splitter (PBS) based on the horizontal triple-slot waveguides is proposed and optimized by using the rigorous H-field-based full-vectorial finite element method and the least-squares boundary residual method. It can be noted from the simulation results that a fabrication-tolerant PBS with a compact length of 33 μm can be yielded based on the horizontal triple-slot waveguides. The polarization extinction ratios are -21.8 and -20.3 dB at 1.55 μm wavelength for the quasi-TE and quasi-TM modes, respectively. The 1 dB bandwidth is 100 nm for both the polarizations. The fabrication tolerances are also thoroughly calculated for the proposed PBS.
