We propose a simple directly modulated laser transmitter which is compatible with existing communication standards and extends the reach of commercially available directly modulated diode lasers by an order of magnitude to the important 10GHz, >80 km range. More than fifty percent savings in cost and size, power consumption and weight are anticipated relative to the predominant LiNbO3 based technology. Furthermore, the new technology results in reduced number of optical components at the transmitter side thereby improving the reliability and ruggedness needed in government secure communication systems. Terrestrial DOD data communication systems, high bandwidth fly-by-light and on-ship communication systems, fiber-based missile guidance systems, phased array radar systems as well as Anticipated Benefits/Commercial Applications: The performance and functionality of fiber optical components have improved significantly in the last few years due to a significant surge in this market. In the current status of the market however improvements in cost, power consumption and size are compelling value propositions as carriers are avoiding any new infrastructural investment such as central offices etc. The proposed project significantly benefits this market by essentially eliminating external modulators in large segments.
