This paper reviews technological options for the modulation formats for serial optical
transmission of 100Gb/s and beyond. In the first part an overview on various modulation …

We investigated through simulations the performance of Nyquist-WDM Terabit
superchannels implemented using polarization-multiplexed phase shift-keying based on 2 …

In this tutorial overview, the principles, advantages, challenges, and practical requirements
of optical orthogonal frequency division multiplexing (OFDM)-based optical access are …

Fast advancing silicon technology underpinned by Moore's law is creating a major
transformation in optical fiber communications. The recent upsurge of interests in optical …

We discuss the generation, wavelength-division-multiplexed (WDM) long-haul transmission,
and coherent detection of 224-Gb/s polarization-division-multiplexed (PDM) 16-ary …

We propose a novel coherent optical orthogonal frequency-division multiplexing (CO-
OFDM) scheme with reduced guard interval (RGI) for high-speed high-spectral-efficiency …

We report successful transmission of dual-LP_11 mode (LP_11a and LP_11b), dual
polarization coherent optical orthogonal frequency-division multiplexing (CO-OFDM) signals …

A wavelength tunable optical comb is generated based on the gain-switching of an
externally seeded Fabry-Pérot laser diode. The comb consists of about eight clearly …

In addition to the dimensions of time, frequency, complex constellation, and polarization,
spatial mode can be the fifth dimension to be explored for modulation and multiplexing in …

We describe in more detail a novel InP-based comb generator for optical orthogonal
frequency division multiplexed (OFDM) transmission. The device integrates a Mach …
