Industry’s First Terabit Optical Link

Technical Paper

An Error-free 1 Tbps WDM Optical I/O Chiplet and Multi-wavelength Multi-port Laser

In this paper we demonstrate a 128 Gbps/port (8-λ×16 Gbps/λ) natively error-free transmission across eight optical ports using a 8-port, 8-λ/port WDM remote laser source and a pair of monolithically integrated CMOS optical I/O chiplets with 4.96-5.56 pJ/bit optical Tx+Rx chiplet energy efficiency.
