| Abstract: | Ultrathin vertical-structure GaN Light Emitting Diode (LED) that can enhance light extraction efficiency as well as modulation bandwidth is a key optical element for visible light communication. In order to meet the requirement of underwater blue light communication, vertical-structure blue LED is designed and fabricated according to subwavelength vertical structure LED model. The fabricated vertical-structure LED can achieve a transmission rate of 10 Mbps under the NRZ-OOK modulation scheme. Furthermore,this vertical-structure LED is used to establish an underwater blue light communication system, which can achieve a full-duplex data communication with a modulation rate of 2 Mbps. |
