“…Although different in application, recent published chips with similar requirements integrate a great number of optical power monitors and phase shifters. For example, two recent demonstrations integrate 900 optical power monitors and 448 phase shifters [44], and 1024 phase shifters [45], respectively in footprints lower than 300 mm 2 .…”

“…Recently we demonstrated a 32 × 32 T-O MZI switch fabric based on a new topology named hybrid dilated Benes [76]. With this unique topology, the switch fabric achieves quite low optical crosstalk but with fewer switch cells.…”

“…Unlike the optical transceivers, the optical switch chips require large-scale, high-density control, optical and electrical package. We demonstrated a prototype of fully-assembly, fully-functional T-O 32 × 32 hybrid dilated Benes silicon photonic switch fabric [76,102,103]. For the optical package of high-port fiber array, there are several potential methods including the mechanically compliant evanescent polymer coupler [104,105,106], the hexagonal PROFA [84], the extremely-high-Δ (5.5%) PLC fiber array connector [71] and the silica mode field adapter/fiber spacing concentrator (FSC) [103].…”

In the last decade, silicon photonic switches are increasingly believed to be potential candidates for replacing the electrical switches in the applications of telecommunication networks, data center and high-throughput computing, due to their low power consumption (Picojoules per bit), large bandwidth (Terabits per second) and high-level integration (Square millimeters per port). This review paper focuses on the state of the art and our perspectives on silicon photonic switching technologies. It starts with a review of three types of fundamental switch engines, i.e., Mach-Zehnder interferometer, micro-ring resonator and micro-electro-mechanical-system actuated waveguide coupler. The working mechanisms are introduced and the key specifications such as insertion loss, crosstalk, switching time, footprint and power consumption are evaluated. Then it is followed by the discussion on the prototype of large-scale silicon photonic fabrics, which are based on the configuration of above-mentioned switch engines. In addition, the key technologies, such as topological architecture, passive components and optoelectronic packaging, to improve the overall performance are summarized. Finally, the critical challenges that might hamper the silicon photonic switching technologies transferring from proof-of-concept in lab to commercialization are also discussed.

“…Waveguide crossings are a key building block for the realization of photonic integrated circuits (PICs) with higher functional complexity e.g. in photonic networks [1][2][3]. This holds especially true for PICs that require end facet coupling, which inherently sets limitations in the layout options.…”

Broadband low loss and ultra-low crosstalk waveguide crossings are a crucial component for photonic integrated circuits to allow a higher integration density of functional components and an increased flexibility in the layout. We report the design of optimized silicon nitride waveguide crossings based on multimode interferometer structures for intersecting light paths of TE/TE-like, TM/TM-like and TE/TM-like polarized light in the near infrared wavelength region of 790 nm to 890 nm. The crossing design for diverse polarization modes facilitates dual polarization operation on a single chip. For all configurations the loss of a single crossing was measured to be~0.05 dB at 840 nm. Within the 100 nm bandwidth losses stayed below 0.16 dB. The crosstalk was estimated to be on the order of −60 dB by means of 3D finite difference time domain simulations.
