|The 2019 Optoelectronics chapter covers data transmission that utilizes optical technology over optical fiber and other waveguides across distances of thousands of kilometers down to a few millimeters (on-chip). It also includes information about free space optical communication used within a room and between spacecraft over interplanetary distances.
This comprehensive chapter discusses optical data transmission applications such as: telecommunications, fiber to the X (including cable TV), local area networks, data centers, plastic optical fiber (automotive), active optical cables, backplanes, on-card optical I/O, optical transmission into and out-of package, on-chip interconnect, and transmitting data through free space.
It also highlights how optical data transmission continues to improve and displace copper on four fronts:
1) Becoming technically and economically viable for shorter and shorter distances
2) Lowering the energy required to transmit data optically, which is becoming more important
3) Enabling transmission of higher data rates
4) Achieving the I/O data density (Gb/s per mm2) attainable with optical methods is needed for anticipated devices of the future
