Microring-based optical switches are promising for wavelength-selective switching with the merits of compact size and low power ***,the large insertion loss,the high fabrication,and the temperature sensitivity hinder the scalability of silicon microring optical switch *** this paper,we utilize a three-dimensional(3D)microring-based optical switch element(SE)on a multi-layer Si_(3)N_(4)-on-SOI platform to realize highperformance large-scale optical switch *** 3D microring-based SE consists of a Si∕Si_(3)N_(4) waveguide overpass crossing in the bottom and the top layers,and Si_(3)N_(4) dual-coupled microring resonators(MRRs)in the middle *** switch is calibration-free and has low insertion *** the 3D microring-based SEs,we implement an 8×8 crossbar optical switch *** the resonance wavelengths of all SEs are well aligned,only one SE needs to be turned on in each routing path,which greatly reduces the complexity of the switch *** optical transmission spectra show a box-like shape,with a passband width of~69 GHz and an average on-state loss of~0.37 *** chip has a record-low on-chip insertion loss of 0.52-2.66 *** also implement a non-duplicate polarization-diversity optical switch by using the bidirectional transmission characteristics of the crossbar architecture,which is highly favorable for practical applications.100 Gb/s dual-polarization quadrature-phase-shift-keying(DP-QPSK)signal is transmitted through the switch without significant *** the best of our knowledge,this is the first time that 3D MRRs have been used to build highly scalable polarization-diversity optical switch fabrics.

Addressing the wavelength locking application scenario for massive-scale micro-ring modulator arrays, this paper proposes a high-speed signal modulation voltage swing adaptive wavelength locking technique for microring modulators. Through simulations and experimental analysis, the effect of modulation voltage swing on the curve of average optical power versus input wavelength is analyzed, and the modulation voltage swing adaptive wavelength locking method based on STM32 is experimentally validated.
