Baseline Link Calculation for Optical Broadcasting through Water

Abstract

A link calculation is carried out to determine whether present blue- green technology can support wide-area broadcasting from satellite to oceanic underwater receivers a bit-per-second rates; and to determine what improvements, beyond the status of technology assumed, would be most productive a making such broadcasting possible. The link technology today is tens of dB away from supporting a wide-area broadcast service; the most productive direction for developmental technology is in producing a suitable, efficient laser source with one hundred watts or more of average power output.
