In this letter, we report the design, fabrication, and measurement of a silicon photonics-based transmitter (Tx) offering both mass production capability and high integration level potentiality. The Tx circuit consists of an integrated photodiode generating a 200-300-GHz signal for photonic upconversion from baseband to millimeter-wave. This Tx...

In this Letter, the authors report the achievement of terahertz transmissions using advanced quadrature amplitude modulation (QAM)16 signals using 300 GHz silicon photonics devices, developed in industrial foundry process PIC25G. Up to 56 Gbps is obtained using QAM16 single channel modulation and up to 50 Gbps in a dual-channel configuration.

With the surge in mega-data communications, wireless networks are entering a revolution which has now taken off with 5G. From a user perspective, the main challenge is providing fast and agile connections in all usage scenarios. Considering the data-rates expected to be delivered to users (some urban areas with 1000 users per cell) the overall...
