Summary: To achieve complex functionality in small size, weight and power, photonic integrated circuits (PIC) are being expanded from two-dimensional to three-dimensional. This paper proposes a new design for a scalable 3D silicon optical switch, using key elements such as silicon electro-optic switches and crossings to optimize the optical switching network. The architecture is based on CLOS architecture and can be extended to multiple layers. The experimental results show that the proposed design is scalable and can improve interconnect density.

Summary: A novel 1 x M fold-back type wavelength selective switch (WSS) is designed to have fewer waveguide crossings, reducing excess crosstalk and loss in lightwave circuits. By using a fold-back architecture, the number of crossings can be reduced to less than half of a conventional design, improving performance and scalability. The switching operation of a 200-GHz spacing, 20-channel, 1 x 2 silicon WSS in a fold-back configuration is demonstrated, showing promising results with average insertion loss and extinction ratio.

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.
