Underwater wireless communication has many fold applications including oceanography, seashore oil well exploration, researches in sea water living organs and so on. In this paper we have proposed a high-speed underwater optical wireless communication (UOWC) using 80 μm blue-emitting GaN-based micro-LEDs.   We have obtained 100 Mb/s data communication speed with areceived light output power of -- 40 dBm and a BER of 1.9 × 10−3, suggesting that UOWCwith extended distance can be achieved.  Our experimental results illustrated that a 200 Mb/s data rate with aBER of 3.0 × 10−6 at an underwater distance of 5.4 m.
