Project Description

​Recently, underwater wireless optical communication (UWOC) has been proposed as an alternative or complementary solution to acoustic and radio frequency (RF) underwater communication links over short and moderate distances (<100m) to alleviate the current problem of low data rate and large transmission delays. UWOC uses visible blue-green (400-550 nm) laser diodes to establish secure, efficient and high data rate communication systems. However, the underwater environment is optically very challenging. The propagation of laser beams in seawater is significantly affected by absorption scattering, and turbulence. In KAUST, we are experimentally addressing these challenges. We developed an experimental test-bed in the laboratory with an embedded water tank to simulate the ocean environment. ​​​​

Professor, Electrical and Computer Engineering

Boon S. Ooi
​Professor Ooi's research is primarily concerned with the study of semiconductor lasers and photonic integrated circuits. Specifically, he has contributed significantly to the development of practical technologies for semiconductor photonics integrated circuits, and the development of novel broadband semiconductor lasers, multiple-wavelength lasers and superluminescent diodes. Most recently, he focuses his research on the areas of GaN-based nanostructures and lasers for applications such as solid-state lighting and visible light communications.

Desired Project Deliverables

​Students involved will focus on developing experimental and theoretical models tobetter understand the underwater optical channel and the effects of turbulence, absorption, and scattering in different waters and at different depths. In particular, the focus is on investigating bit error rate (BER) performance under air bubble, temperature and salinity induced oceanic turbulences, and developing a comprehensive and unified statistical turbulence model for the ocean.​
