“…Zhang etc. presented a WSS based on arrays of adiabatic elliptical microring, enabling the selection of arbitrary wavelength-channel for any port leveraging the thermo-optic effect and fine wavelength-tuning linearity [9]. Wavelength-selective switches based on silicon microring resonators typically utilize the wavelength-selective characteristics of the microring.…”

The past decades have witnessed the remarkable development of the optical communications and optical networking. In response to the ever-increasing demands for larger bandwidth and enhanced routing flexibility of optical network, the wavelength selective switch (WSS) was assumed as a critical role in wavelength control and flexible/elastic optical networking. Here, we proposed an integrated all optical lithium-niobate-on-insulator (LNOI) WSS including a 1 × 4 micro ring resonators (MRRs) in the C-band. A non-volatile wavelength-selective tuning process fully controlled by intense light at cryogenic temperature was introduced based on the photorefractive effect. This offers the possibility of realizing of next generation large-scale wavelength division multiplexing (WDM) network and optical add-drop multiplexer (ROADM) system.

Wavelength-selective switches (WSS) have large potential applications in future high-capacity, low-latency, flexible, and energy-efficient data center optical networks. Here, a novel ultracompact 1 × N polarization-insensitive WSS is proposed on the silicon-on-insulator (SOI) platform. The WSS comprises one input port with a polarizing beam splitter and rotator (PBSR), two identical (M × N + 1) × (M + N) arrayed waveguide gratings (AWGs) cascaded with M 1 × N thermo-optic (TO) switches, and N output ports with polarization combiners. The AWG works as both a demultiplexer and multiplexer to eliminate the center wavelength mismatch induced by fabrication errors and to achieve an ultracompact footprint. The TO switches placed on loopback arms allow for the routing of each wavelength to any one of the N output ports. A new design of leveraging the I/O waveguide spacing difference between the loopback inputs and demultiplexing outputs of AWG is employed to eliminate waveguide crossings in a conventional WSS layout design. In experiment, a 12-channel 400 GHz spacing 1 × 2 WSS with a footprint of 1.67 × 1.7 mm 2 is demonstrated. The minimal on-chip loss of 6.8 dB, best extinction ratio of 25 dB, and switching speed of 42 μs are achieved. The measured polarization-dependent loss is <0.5 dB and polarizationdependent wavelength shift is <0.08 nm.
