Intensity modulation and direct detection (IM-DD) systems are widely used in short-reach optical networks. Thus, developing a practical and accurate method to characterize nonlinear distortion and …
In order to keep up with expected growth in data traffic, using multiple bands beyond the C band is an appealing solution as it can partly reuse deployed optical fibers. One way of handling multi-b…
Enabled by an autonomous calibration mechanism, crosstalk-free (−38.5 dB) fabrication-tolerant 32-ch DWDM demultiplexer on a standard Si PIC platform is demonstrated for the first time. On this p…
An optical digital-to-analog converter (DAC) is a promising solution for the efficient generation of multilevel modulation signals without a high-speed electrical DAC and a large swing linear drive…
