Celebrating the 20^ th anniversary of Optics Express, this paper reviews the evolution of
optical fiber communication systems, and through a look at the previous 20 years attempts to …

We review the use of optical frequency combs in wavelength-division multiplexed (WDM)
fiber optic communication systems. In particular, we focus on the unique possibilities that are …

A novel and cost effective optical multicarrier (OMC) generator is introduced in this article.
OMC is generated by connecting three modulators in cascade with laser source, where laser …

The generation of optical frequency comb (OFC) with novel controlled delay circuit is
presented in this study. The proposed OFC is based on a single laser source which is …

In this article we have proposed a novel cost effective optical frequency comb (OFC)
generator by using pair of Mach zehnder modulators (MZMs) in cascaded configuration with …

High-speed transoceanic optical fiber transmission using direct modulation (DM) and direct
detection (DD) was one of the most stirring breakthroughs for telecommunication in 1990s …

Recirculating frequency shifter (RFS) loops can be used for electronically programmable,
variable-spacing multiline spectrum generation, which can benefit the development of fully …

A new approach for realizing a wideband optical frequency comb (OFC) generator based on
driving cascaded modulators by a Gaussian-shaped waveform, is proposed and numerically …

This work presents a design for a binary driven optical square M-ary quadrature amplitude
modulation (QAM) transmitter for high speed optical networks. The transmitter applies …

Optical networks, for 400G and beyond, require flexibility and agility from network elements,
especially from coherent transceivers. Higher baud rates are made possible using new …
