80 Gb/s free-space reconfigurable optical interconnects with carrierless-amplitude-phase modulation and space- time block code

Carrierless-amplitude-phase modulated and space-time coded free-space reconfigurable optical interconnects with extended range and reduced inter-channel crosstalk are experimentally demonstrated. Results show that 80 Gb/s interconnect is achieved and the error-free distance is improved by about 65%.
