Today's optical communication systems are fast approaching their capacity limits in the
conventional telecom bands. Opening up new wavelength bands is becoming an appealing …

A transparentOptical-subTHz-Optical link providing record-high single line rates of 240
Gbit/s and 192 Gbit/s on a single optical carrier over distances from 5 to 115 m is …

This tutorial paper reviews advanced modulation techniques that have been proposed in the
literature for the implementation of flexible (or reconfigurable) transceivers, which are …

We demonstrate for the first time transmission of 54 Gbit/s and 48 Gbit/s over 44 km and 150
km, respectively, utilizing an optical bandwidth of only 3 GHz. We used polarization division …

As one of the promising multiplexing and multicarrier modulation technologies, Nyquist
subcarrier multiplexing (Nyquist SCM) has recently attracted research attention to realize …

We demonstrate a remotely seeded flexible passive optical network (PON) with multiple low-
speed subscribers but only a single optical line terminal transceiver operating at a data rate …

We propose and demonstrate a new low-complexity hardware architecture and digital signal
processing (DSP) implementation for coherent reception of Nyquist frequency division …

We proposed and implemented a bandwidth-economic coherent optical transmission
technology using optical independent-sideband (O-ISB) modulation. Generation of two …

We demonstrate full flex-grid operation with Nyquist frequency division multiplexing. The
technique supports high spectral efficiency, asynchronous operation of channels, variable …

Consistent with an aspect of the present disclosure, electrical signals or digital subcarriers
are generated in a DSP based on independent input data streams. Drive signals are …
