Colorless, directionless, and contentionless reconfigurable optical add/drop multiplexing (CDC-ROADM) provides highly flexible physical layer network configuration. Such CDC-ROADM must operate in multiple wavelength bands which are being increasingly

While ultrahigh-baud-rate optical signals are effective for extending the transmission distance of large capacity signals, they also reduce the number of wavelengths that can be arranged in a band because of their wider bandwidth. This reduces the fl

We developed a multilane photonic spectral processor array integrated with a spatial and planar optical circuit platform. This device enables individual control of the optical power in the spatial and wavelength domains by controlling the phase patte

We propose an asymmetric three-dimensional modulation for multi-lane IM-DD transmission. Simulation results show that the proposed scheme enables multi-lane 112-Gb/s PAM signals to be tolerant to cumulative dispersion of −200 ps/nm and experimental

We propose a NL-MLSE scheme using a third-order Volterra filter that estimates channel non-linearities to improve bandwidth-limitation and chromatic-dispersion tolerances. NL-MLSE with three memories achieves 192-Gb/s PAM-4 transmission with 96-Gsamp

We achieve 180-Gb/s PAM-4 transmission under 32-GHz bandwidth limitation applying MLSE based on 3-memory T-spaced 2nd order Volterra filter. We experimentally demonstrate 2.88-Tb/s O-band transmission using 4-λ LAN-WDM and SDM over 2-km 4-core fiber

We propose a novel optics for integrated wavelength selective switch (WSS) array that suppresses inter-sub WSS crosstalk for space-division multiplexed network. A crosstalk level of as low as −50 dB has been achieved.
