“…Pulse sequences can be generated by filtering the frequency comb of a mode-locked laser [7], [8], by a Nyquist laser [4], by the generation of frequency combs with parametric effects [9], [10], or by one or two coupled intensity modulators that are driven with one or multiple radio frequencies [1], [13] - [23]. Especially the last method offers the possibility for integrated Nyquist pulse sources [15], [16], [19], and [20].…”

“…It reveals a slightly better performance with lesser error for the 9-line scenario. Even for a three-line comb generation by integrated silicon modulators, a ripple of just 0.04 dB has been shown in [16]. However, the ripple might increase to 1.83 dB for coupled modulators and other integrated designs [15].…”

“…Owing to the advantages of easy implementation, near-ideal rectangular spectrum, higher roll-off factor, and tunable repetition rate, numerous designs have been proposed based on this basic idea [13]- [18].

“…Besides communications, the temporal and spectral features of the pulse sequences like multi-wavelength operation and tunable repetition rate make them suitable to be used as a sampling source in photonic analog-to-digital (ADC) and digital-to-analog conversion (DAC) [16] - [18], [21] - [23] and as sampling pulses for the demultiplexing of Nyquist optical time-division multiplexing (OTDM) signals [24].…”

Optical sinc-shaped Nyquist pulses are widely used in microwave photonics, optical signal processing, and optical telecommunications due to their numerous advantages, like rectangular shape in the frequency domain, the orthogonality and the consequential possibility to use these pulses to transmit data with the maximum possible symbol rate. Ideal sinc pulses with the rectangular spectrum are just a mathematical construct. However, high-quality sinc pulse sequences offer the same advantages and can be generated by a phase-locked rectangular frequency comb with mode-locked lasers, intensity modulators, and integrated devices. Nevertheless, any non-idealities in the pulse and comb generation might lead to a degradation of the system performance, especially for metrology. Here, we investigate and analyze the effect of three major non-idealities, namely, the roll-off factor, the side band suppression ratio (SSR), and the ripple of sinc-shaped reconfigurable optical Nyquist pulse sequences based on 3, 5, and 9-line optical phase-locked frequency combs. We compare these results with the existing literature for the three-line comb followed by the experimental verification of the simulation results. We illustrate that by increasing the number of comb lines, the pulse sequences have superior performance and contribute to lesser root-mean-square (r.m.s.) error. We also discuss the trade-off between the r.m.s. error and the optical power loss for increasing the SSR.INDEX TERMS Nyquist pulse, optical frequency combs, ripple, side band suppression, optical sampling.

Filterless and Compact ANy-WDM Transmission System Based on Cascaded Ring Modulators

To cope with the exponential increase in internet services and corresponding data traffic, especially data centers and access networks require new high data rate transmission methods with low cost, very small package and low energy consumption. In this paper, we demonstrate a filterless, agnostic Nyquist wavelength division multiplexing (ANy-WDM) transmission system based on cascaded ring modulators and a comb source. The single ring modulator acts as a filter, filtering one of the n WDM lines, generated by the comb. The same ring modulator modulates k time division multiplexed (TDM) channels on the single wavelength. Since each WDM channel, consisting of k time domain channels, has a rectangular bandwidth, the aggregated symbol rate of the superchannel modulated by this system corresponds to the optical bandwidth of all n WDM channels together. The approach is very simple and compact. Since no optical filters, delay lines or other special photonics or high bandwidth electronics is needed, an integration into any photonics platform is straightforward. Thus, the proposed method might enable very compact, ultrahigh data rate transmission devices for future data centers and access networks.INDEX TERMS Integrated photonics, Nyquist transmission, ring modulators, WDM.
