High-speed silicon micro-ring modulators (MRMs) have recently emerged as an attractive alternative to traditional modulators due to their compact size and low power consumption. We demonstrate an MRM is a promising candidate for the next generation short-reach optical networks beyond 100 Gbaud per channel optical interconnects.
Multi-wavelength laser sources have gained significant interest for future high-bandwidth density DWDM optical links, enabling improved energy efficiency and bandwidth scaling. In this work, we present an integrated III-V/Si hybrid four-wavelength DFB laser with 200 GHz wavelength spacing and <10 dBm output power per wavelength. The wavelength spacing and total output power variations are <±25 GHz and <1 dB, respectively, for an ambient temperature change of 30°C. We also measured the relative intensity noise (RIN) and Lorentzian linewidth of the laser to be <-135 dB/Hz and <300 kHz, respectively.
Data center IP traffic is doubling every 2.5 years, driving the need to scale connectivity bandwidth on a similar cadence. At higher data rates the electrical link reach shrinks but energy efficiency does not improve significantly. Co-packaging optics close to ASICs enables data throughput scaling by reducing the SERDES power and hence overall power due to shorter electrical channels. Despite the advantages, co-packaging optics next to electronics can be challenging. This paper reviews Intel’s advancements in demonstrating industry’s first fully operational Silicon Photonic integrated circuit co-packaged with switch ASICs, describing in detail component level, integrated photonic integrated circuit (PIC) level, and transceiver module level design and performance.
In this project the viability of an optically-enhanced chassis providing n × 10 Gbit/s bandwidth for both point-to-point
and broadcast communication between servers is determined.
In this paper, we propose a monolithic optical front-end for soft-decision low-density parity-check (LDPC) decoders
based on 112 Gb/s polarization division multiplexed quadrature shift keying (PM-QPSK) coherent detection. The novel
front-end is a low complexity and low cost solution with a performance improvement of 6.4 dB over system without the
use of coding. The front-end also outperforms the conventional RS(255,239) based codes by 1.3 dB at the BER of 10-8.
