In this paper, we experimentally demonstrate the transmission of 56 Gbaud four-level pulse
amplitude modulation (PAM4) signal over 2-km single mode fiber (SMF) with intensity …

Over the last decades, the annual global internet protocol (IP) traffic has been increasing at
an enormous rate and is going to further increase. Overall IP traffic will grow at a compound …

In today's fiber-optic communication systems, the bandwidth of the photonic components, ie
modulators and photo diodes, is way greater than that of their electrical counterparts, ie …

Digital-to-analog converters (DACs) for high-speed optical communication systems based
on CMOS technology have bandwidths lower than nowadays electro-optic components. A …

This article describes a frequency-interleaved digital-to-analog conversion technique named
bandwidth tripler with an image-rejection analog multiplexer (AMUX). The tripler extends the …

The concept of frequency interleaving (FI) for digital-to-analog converters (DACs) has
recently experienced renewed interest, in order to overcome the DACs' bandwidth …

This paper presented the optimal minimax and weighted least squares (WLS) methods for
designing digital finite impulse response (FIR) filters to reduce the aliasing errors generated …

Bandwidth interleaving digital-to-analog converter (BI-DAC) is a new method for breaking
through the bandwidth restriction of the DAC to generate a wideband signal. However, there …

We have proposed a transmitter using bandwidth interleaving for high-speed optical
communications. Baseband signals generated at two digital-to-analog converters are …

Next generation wireless communication systems such as fifth generation mobile
communications and high throughput satellites have promised a step increase in the rate at …
