Low power consumption silicon photonics datacenter interconnects enabled by a parallel architecture

Abstract

An architecture is presented for realizing 1 Tbps datacenter interconnects using energy efficient silicon photonic ring modulators and QD-MLL. Both these components show excellent agreement with design parameters. High efficiency EO tuners are also reported.

An Energy-Efficient and Bandwidth-Scalable DWDM Heterogeneous Silicon Photonics Integration Platform

“…More and more groups share and resonate the same vision with us and are developing different versions of frequency comb-powered, microring resonator-based DWDM direct detection TRx architectures, chips [119,120] and product [121][122][123]. Future work on fully functional TRx system integration including electronic driver integration and system-level control algorithm development brings new challenges and excitement as well.…”

Regeneration of 200 Gbit/s PAM4 Signal Produced by Silicon Microring Modulator (SiMRM) Using Mach–Zehnder Interferometer (MZI)-Based Optical Neural Network (ONN)

“…Therefore, the entire Hilbert space in the Reck mesh can be written as Equation (5). Hence, the input-output relationship of the MZI network can be expressed as Equation (6), where Y represents the output optical field matrix, X is the input optical field matrix, and H denotes the Hilbert space matrix. This operation is like the fully connected layer shown in Figure 3.…”

“…For beyond 1 Tbit/s transmission [4], a single-lane data rate at or beyond 200 Gbit/s is required with improved power and space efficiencies [5]. Nowadays, silicon photonics (SiPh) is widely considered as one of the important optical integration technologies for the next generation data center optical networks and optical interconnects [6][7][8][9][10][11]. SiPh devices consume less power and produce less heat than conventional electronic circuits, offering great advantages of energy-efficient bandwidth upgrade.…”

High-Performance Silicon Photonics Using Heterogeneous Integration

“…1) InP/Si QW Mode-Locked Lasers: Heterogeneously integrated III-V/Si mode-locked lasers using integrated mirrors do not rely on cleaved or polished facets for laser feedback, and hence the mode spacing can be controlled quite accurately, such that with slight tuning of the gain current, a desired spacing can be achieved with high yield [67]. Saturable absorbers can be implemented directly using the laser gain material by reverse biasing.…”
