A team of researchers from the George Washington University and University of California, Los Angeles, have created and demonstrated a photonic digital to analog converter without leaving the optical domain.
Optoscribe has launched a monolithic glass chip for low-loss coupling to silicon photonics (SiPh) grating couplers.
This paper describes how silicon photonic (SiPh) opto-electronic integration and packaging, with its improved RF performance, is designed to enable next-generation coherent transmission beyond 100Gbaud and provide network operators with the ability to avoid “half-step” capacity upgrades and allow them the full step upgrades they need without sacrificing reach or stranding network bandwidth when migrating from current-generation solutions.
A team of researchers from the University of Southampton's Optoelectronics Research Centre (ORC) have demonstrated the first all-silicon optical transmitter at 100Gb/s and beyond without the use of digital signal processing (DSP).
Technology research institute, CEA-Leti has demonstrated a fully packaged CWDM optical transceiver module with data transfer of 100Gb/s per fibre.
Silicon photonics foundry service provider, CompoundTek has expanded to open a silicon photonics test facility in Singapore.
AOI is demonstrating the feasibility of its silicon photonics platform for OBO requirements.
Molex Ventures is making a strategic investment and collaboration between the Molex Optical Solutions Group and Elenion Technologies in order to jointly develop, manufacture and promote silicon photonic-based product solutions.
Will silicon photonics live up to its promises? Pauline Rigby investigates
Silicon photonics is on the verge of experiencing dramatic uptake in optical transceivers, market research firm Yole Développement has reported, with the technology set to capture 35 per cent – almost $4 billion – of the optical transceiver market by 2025, up from just a few per cent in 2016.
The transceivers are expected to be used mostly for intra-data centre communication, according to Yole, with the strongest demand being for 400G (400 Gigabits per second), and 200G acting as an intermediate step between 100G and 400G.
