We quantify, through simulations and experiments at 21.4 GBaud, the effect of in-band
crosstalk on several advanced optical modulation formats, showing a 1-dB penalty at a bit …

We demonstrate high speed optical transmission systems using digital coherent detection at
all-electronically multiplexed symbol rates of 80 and 107 Gbaud. At 107 Gbaud, we …

Since it is difficult to emit a control a IQ modulator emitting modulated lightwave according to
QAM format without signal degradation of said emitted signal due to low frequency dither …

Long-haul communication systems are requiring more and more spectral efficiency as data
rates increase. QAM-16 is a promising candidate for each wavelength in a Wavelength …

We generate a single-carrier 21.4-Gbaud polarization-division-multiplexed (PDM) 64-ary
quadrature-amplitude-modulated (QAM) signal (256.8-Gb/s line rate) using a single in …

We demonstrate generation and transmission of optical signals by directly interfacing highly
efficient silicon-organic hybrid (SOH) modulators to binary output ports of a field …

The architecture and performances of a multilevel driver for pulse amplitude modulation
(PAM) formats, designed and fabricated in 0.7 µm InP double‐heterojunction bipolar …

Power-digital-to-analog converters (DAC) circuits for high capacity and high spectral
efficiency optical transmitters are presented in this paper. They are based on a 0.7-μm InP …

In this paper, we describe a new type of digital-to-analog converter (DAC) for optical
wireless communication. Conversion occurs in the optical rather than the electrical domain …
