Terabit/sec VCSEL-based parallel optical module based on holey CMOS transceiver IC

We report a 24 TX + 24 RX transceiver underpinned by a “holey” CMOS IC. All channels operate at 20 Gb/s (BER <;10<sup>-12</sup>, 7.3 pJ/bit) achieving record aggregate bidirectional bandwidth for parallel transceivers: 0.48 Tb/s.
