Special Issue Information

Dear Colleagues,

Emerging applications such as cloud-based storage services, high definition streaming services, machine-to-machine communications, and 5G radio networks are fueling the need for faster, low latency and bandwidth-efficient optical networks. The requirements of these applications include increased capacity and reduced cost, power consumption, footprint, and complexity. Therefore, there is a growing trend in developing integrated optoelectronic devices to meet the above-mentioned requirements.

The need for rapid and accurate detection of analytes is also increasing for environment monitoring, food and drug quality control, and medical diagnosis. Significant advances, driven by the need to reduce cost, increase portability, and provide rapid results, have been made in the field of sensing by leveraging integrated photonics.

For this Special Issue, you are invited to submit research papers on advances in integrated photonics for communication and sensing applications. Specific areas of interest in the topic include (but are not limited to) the following:

  • Photonics for massive connectivity;
  • Short reach optical interconnects;
  • Optical access technologies; 
  • Nanophotonics and plasmonic;
  • Photonic sensors.

Abstract
We present a systematic comparison of PAM-2 (NRZ), Duobinary-PAM-2, PAM-4, and Duobinary-PAM-4 (duo-quaternary) signaling in the context of short-reach photonic communications systems using a Mach–Zehnder modulator as transmitter. The effect on system performance with a relaxed and constrained system’s opto-electronic bandwidth is analyzed [...] Read more.
We present a systematic comparison of PAM-2 (NRZ), Duobinary-PAM-2, PAM-4, and Duobinary-PAM-4 (duo-quaternary) signaling in the context of short-reach photonic communications systems using a Mach–Zehnder modulator as transmitter. The effect on system performance with a relaxed and constrained system’s opto-electronic bandwidth is analyzed for bit rates ranging from 20 to 116 Gb/s. In contrast to previous analyses, our approach employs the same experimental and simulation conditions for all modulation formats. Consequently, we were able to confidently determine the performance limits of each format for particular values of bit rate, system bandwidth, transmitter chirp, and fiber dispersion. We demonstrate that Duobinary-PAM-4 is a good signaling choice only for bandwidth-limited systems operating at relatively high speed. Otherwise, PAM-4 represents a more sensible choice. Moreover, our analysis put forward the existence of transition points: specific bit rate values where the BER versus bit rate curves for two different formats cross each other. They indicate the bit rate values where, for specific system conditions, switching from one modulation to another guarantees optimum performance. Their existence naturally led to the proposal of a format-selective transceiver, a component that, according to network conditions, operates with the most adequate modulation format. Since all analyzed modulations share similar implementation details, signaling switching is achieved by simply changing the sampling point and threshold count at the receiver, bringing flexibility to IM/DD-based optical networks.
