“…However, this approach would require, e.g. 16 lanes at 25 Gb/s in order to achieve the 400 Gb/s target, thereby making it challenging to meet 400 Gb/s form-factor pluggable (e.g., CDFP2 and CDFP4) requirements on power consumption and footprint [3], [4]. Therefore, it is crucial to develop other solutions for beyond 100 Gb/s data links satisfying these industry requirements in terms of footprint, power consumption, and cost efficiency.…”

Short range optical data links are experiencing bandwidth limitations making it very challenging to cope with the growing data transmission capacity demands. Parallel optics appears as a valid short-term solution. It is, however, not a viable solution in the long-term because of its complex optical packaging. Therefore, increasing effort is now put into the possibility of exploiting higher order modulation formats with increased spectral efficiency and reduced optical transceiver complexity. As these type of links are based on intensity modulation and direct detection, modulation formats relying on optical coherent detection can not be straight forwardly employed. As an alternative and more viable solution, this paper proposes the use of carrierless amplitude phase (CAP) in a novel multiband approach (MultiCAP) that achieves record spectral efficiency, increases tolerance towards dispersion and bandwidth limitations, and reduces the complexity of the transceiver. We report on numerical simulations and experimental demonstrations with capacity beyond 100 Gb/s transmission using a single externally modulated laser. In addition, an extensive comparison with conventional CAP is also provided. The reported experiment uses MultiCAP to achieve 102.4 Gb/s transmission, corresponding to a data payload of 95.2 Gb/s error free transmission by using a 7% forward error correction code. The signal is successfully recovered after 15 km of standard single mode fiber in a system limited by a 3 dB bandwidth of 14 GHz.

“…To upgrade the total throughput for 400-Gb/s, three options have been mainly discussed, which are to increase the number of wavelengths (horizontal axis in the figure), to increase the bit rate per wavelength (vertical axis), or to use a higherorder modulation (HOM) format. In the early stage of the discussion, 16λ x 25-Gb/s NRZ was the promising candidate for 400GbE from the perspective of technical similarity to 100GbE [4], [5]. In the latest discussion, the focus has shifted to how to reduce the number of wavelengths by increasing the bit rate of each wavelength and applying HOM.…”

SUMMARYWe review recent progress in integrated photonics devices and their applications for datacom. In addition to current technology used in 100-Gigabit Ethernet (100GbE) with a compact form-factor of the transceiver, the next generation of technology for 400GbE seeks a larger number of wavelengths with a more sophisticated modulation format and higher bit rate per wavelength. For wavelength scalability and functionality, planar lightwave circuits (PLCs), such as arrayed waveguide gratings (AWGs), will be important, as well higher-order-modulation to ramp up the total bit rate per wavelength. We introduce integration technology for a 100GbE optical sub-assembly that has a 4λ x 25-Gb/s non-return-to-zero (NRZ) modulation format. For beyond 100GbE, we also discuss applications of 100GbE sub-assemblies that provide 400-Gb/s throughput with 16λ x 25-Gb/s NRZ and bidirectional 8λ x 50-Gb/s four-level pulse amplitude modulation (PAM4) using PLC cyclic AWGs.
