Abstract
Here, we report on the design and performance of a silicon photonic micro-transceiver required to operate in 5G and 6G environments at high ambient temperatures above 105 °C. The four-channel “IOCore” micro-transceiver incorporates a 1310 nm quantum dot laser system and operates at a data rate of 25 Gbps and higher. The 5 × 5 mm micro-transceiver chip benefits from a multimode coupling interface for low-cost assembly and robust connectivity at high temperatures as well as an optical redundancy scheme, which increases reliability by over an order of magnitude.
Highlights
The conditions required to accommodate the increasing bandwidth densities in 5G+, hyperscale data centers and high-performance computer (HPC) environments are becoming more extreme
In the transmitter section (Figure 4d), an edge emitting a Fabry-Perot Quantum Dot laser diode is passively aligned within a compliant recess in the silicon substrate such that it couples 1310-nanometer continuous wave (CW) light into four single-mode silicon waveguides in the substrate
The Quantum Dot Fabry-Perot Laser Diode (QD-LD) aperture is aligned to a tapered spot size converter (SSC) in the silicon photonic substrate, which allows laser light to couple to the silicon waveguides
Summary
The conditions required to accommodate the increasing bandwidth densities in 5G+, hyperscale data centers and high-performance computer (HPC) environments are becoming more extreme. The compact 5 × 5 mm micro-transceiver chip features a multimode optical coupling interface and an optical redundancy circuit Together, these enable robust, low-cost operation and connectivity at high temperatures and increase reliability by over an order of magnitude compared to non-redundant integrated laser schemes. Integrated photonic solutions for radio applicat can benefit from the current DCI technology, such as single-mode silicon photonic tr ceivers; operating temperatures, power consumption and cost margins wi much more challenging in 5G+ environments going forward and will require new s tions. We provide a detailed technical description of aofm16ultimode con photonics micro-transceiver designed to operate in high-temperature environm with an integrated laser for lower overall power consumption that can meet the strin cost targets of future 5G+ environments due to multimode packaging.
