“…In recent years, focus has moved away somewhat from developing the speed of the modulator, and looking at modulation formats which can fit more data into a modulator with a fixed bandwidth. Popular techniques have included pulse amplitude modulation (PAM) [150], quadrature phase-shift keying (QPSK) [151], quadrature amplitude modulation (QAM) [152] and discrete multitone (DMT) [153]. Concentration has also shifted heavily toward the power consumption of the modulator and design which can be operated with low drive voltages.…”

| In this paper, we present a brief history of silicon photonics from the early research papers in the late 1980s and early 1990s, to the potentially revolutionary technology that exists today. Given that other papers in this special issue give detailed reviews of key aspects of the technology, this paper will concentrate on the key technological milestones that were crucial in demonstrating the capability of silicon photonics as both a successful technical platform, as well as indicating the potential for commercial success. The paper encompasses discussion of the key technology areas of passive devices, modulators, detectors, light sources, and system integration.In so doing, the paper will also serve as an introduction to the other papers within this special issue.

“…In addition, there have been reports on 128 Gb/s PAM-4 transmission system using a multi-electrode silicon photonic Mach Zehnder modulator [4], EML-based 4 lanes of 112.5 Gb/s PAM4 [5], and 112 Gb/s PAM4 Amplifier-free using O-band DML [6]. There are also several reports of DMT transmission over 100 Gb/s, such as our previous work with SiP modulators, where we reached 120 Gb/s on the Oband [7], another SiP modulator achieving 130 Gb/s on C-band (1550 nm) [8], beyond 100 Gb/s transmission of SSB-DMT on O-band [9], 4channel of 100 Gb/s DMT using O band silicon photonic modulator [10], and 100 Gb/s dual side-band DMT with dispersion compensation on C-band [11].There has also been a hybrid PAM/DMT demonstration at 112 Gb/s using a directly modulated laser on Oband [12].…”

We theoretically compare the performance of optical discrete multi-tone (DMT) and pulse amplitude modulation (PAM) using intensity modulated, direct detection (IMDD). PAM is a lower cost, lower complexity solution than DMT, however it is more vulnerable to chromatic dispersion on the C band. We compare DMT and PAM taking into consideration the interplay of laser linewidth, fiber length, transmission rate, and channel bandwidth. We use a semi-analytical model to examine bit error rates. We study how system parameters shift the performance advantages between DMT and PAM. Our model can also be used to find the best hardware solution and frequency band for a target modulation format and bit error rate.

“…Figure 11a illustrates the recovered eye diagram after the receiver's analog-to-digital conversion (ADC) and equalization, which has compensated for the eye closure, while Figure 11b depicts the analytically estimated BER in comparison with an ideal PAM4 reference curve. The BER of 4.6 × 10 −4 is below an FEC threshold of 3.7 × 10 −3 [66,67]. As described in [63], the supported bit rate for this typical system can be much higher than the 1 Gb/s used in this example.…”

Overcoming Challenges in Large-Core SI-POF-Based System-Level Modeling and Simulation

The application areas for plastic optical fibers such as in-building or aircraft networks usually have tight power budgets and require multiple passive components. In addition, advanced modulation formats are being considered for transmission over plastic optical fibers (POFs) to increase spectral efficiency. In this scenario, there is a clear need for a flexible and dynamic system-level simulation framework for POFs that includes models of light propagation in POFs and the components that are needed to evaluate the entire system performance. Until recently, commercial simulation software either was designed specifically for single-mode glass fibers or modeled individual guided modes in multimode fibers with considerable detail, which is not adequate for large-core POFs where there are millions of propagation modes, strong mode coupling and high variability. These are some of the many challenges involved in the modeling and simulation of POF-based systems. Here, we describe how we are addressing these challenges with models based on an intensity-vs-angle representation of the multimode signal rather than one that attempts to model all the modes in the fiber. Furthermore, we present model approaches for the individual components that comprise the POF-based system and how the models have been incorporated into system-level simulations, including the commercial software packages SimulinkTM and ModeSYSTM.
