Abstract

We present a new concept for generating wideband signals of higher spectral efficiency from signals of low-bandwidth and lower efficiency. With pure electronics, we are able to generate broad-bandwidth signals with low-modulation format from low-bandwidth sub-DACs. This is based on electrical orthogonal sampling with sinc-pulse sequences in N parallel branches. In photonics, a higher spectral efficiency can be achieved from M branches at different optical powers. The proposed method can be integrated into any silicon platform and might be of great interest for bandwidth, and data hungry applications.
