Optical spectral reshaping for directly modulated 4-pulse amplitude modulation signals
International audience The tremendous traffic growth in intra/inter-datacenters requires low-cost high-speed integrated solutions. To enable a significantly reduced footprint directly modulated lasers (DMLs) have been proposed instead of large external modulators. However, it is challenging to use D...
