摘要

We propose a novel hybrid plasmonic polarization rotator based on mode interference. Operating at the telecommunication wavelength of 1.55 mu m, the rotation length is very short (3.2 mu m), while the polarization conversion efficiency is as high as 99.5%. The total device insertion loss is only 1.38 dB, much smaller than the common level of plasmonic devices. It also has potential to realize integrated waveplates for various polarization states.

Ultra-compact integrated terahertz modulator based on a graphene metasurface

Myunghwan Kim, Sangin Kim, Soeun Kim

Summary: A new type of mid-infrared ultra-compact optical modulator composed of a graphene metasurface is proposed in this study. Unlike previous schemes, this modulator utilizes the topological characteristic of the isofrequency contour in the hyperbolic metasurface to modulate transmission, providing a modulation depth of 10.7 dB with a length of 750 nm, which is approximately 1/30 of an operating wavelength.

Metamaterial-enabled Fully On-Chip Polarization-Handling Devices

Yaotian Zhao, Jinlong Xiang, An He, Yu He, Xuhan Guo, Yikai Su

Summary: This paper introduces the importance of polarization manipulation in photonic integrated circuits and its wide range of applications in optical communication, nonlinear optics, and quantum optics. By integrating subwavelength-structured metamaterials on optical waveguides using nanofabrication techniques, unprecedented optical manipulation capabilities beyond classical waveguide-based architectures can be achieved. The design of dielectric metamaterials composed of nanoholes and nanoslots allows for competitive performance of key polarization components while maintaining ultra-compact coupling regions. The unique properties of metamaterials provide powerful tools for on-chip polarization manipulation and offer new possibilities for the development of compact and high-performance photonic integrated circuits.

Summary: This study proposes and experimentally demonstrates a dual-polarization and mode-division multiplexed silicon photonic integrated circuit with ultra-small footprint, achieving satisfactory performance parameters within the wavelength range. With pixelated waveguide meta-structures, the device footprint is effectively reduced, and the insertion losses are below 1.4 dB and inter-mode cross talk is below -15 dB over a certain wavelength range.

Summary: Silicon photonics with CMOS compatibility has made significant progress in the past decades and has been widely used in commercial products. To meet the demand for high-fidelity and high-speed optical interconnect, as well as high-resolution sensing and information processing, hybrid integration of existing materials with post-CMOS technology has become crucial. Aluminum nitride (AlN) is a popular piezoelectric material in the field of MEMS and has been studied and integrated into photonic integrated circuits (PICs) in recent years. This review article provides an overview of the properties and processing of AlN thin films, as well as the application of AlN piezoelectric MEMS transducer technologies. Photonic devices on hybrid Si-AlN and pure AlN thin film platforms are also discussed. The article concludes with an outlook on the future development of reconfigurable integrated photonics based on AlN thin films.

A Monolithic Polarization Controller and Tracking Loop for Optical Interconnect Demonstrated on a 90 nm Silicon CMOS-Photonic Platform

Po-Hsuan Chang, Mingye Fu, Peng Yan, Anirban Samanta, Mehmet Berkay On, Yuanming Zhu, S. J. Ben Yoo, Samuel Palermo

Summary: We report the first monolithically-integrated silicon CMOS-photonic co-designed polarization tracking circuit implemented in a 90 nm CMOS SOI process. The circuit utilizes a Polarization Splitter and Rotator (PSR) to decompose the optical input, directional couplers to combine TE components, and thermal phase shifters to maximize optical output. An implemented feedback loop controls the thermal phase shifters, resulting in successful tracking of randomized polarization rotation and achieving a BER of 10(-11) with 10 Gb/s PAM-2 modulation.
