HIGH-POWER FIBER OPTIC SOURCES

THIS PROPOSAL DESCRIBES AN EFFORT TOWARDS DEVELOPING AN OPTICAL SOURCE THAT WILL BE USEFUL IN DIFFERENT FIBER-OPTIC COMMUNICATION NETWORKS. THE DEVICE PROPOSED HERE IS A HIGH POWER E-LED AT 1300NM OPTIMIZED FOR WIDE OPERATING TEMPERATURE RANGE. THE DEVELOPMENT WILL HAVE TWO DISTINCT FOCI: (A) OPTIMIZATION OF THE LED CHIP FOR THE BEST FACET POWER PERFORMANCE; AND (B) DEMONSTRATION OF A PACKAGE THAT WILL ENABLE COUPLING -12DBM AT THE WIDEST TEMPERAATURE RANGE. SINCE HIGH POWER, WHEN ACHIEVED THROUGH STRONG GAIN, IS USUALLY CONTRADICING WIDE OPERATING TEMPERATURE RANGE, AN EFFORT WILL HAVE TO BE MADE TO FIND AN OPTIMUM CHIP STRUCTURE. MRV TECHNOLOGIES, INC.'S BASIC P-SUBSTRATE BURIED-CRESCENT LASER STRUCTURE WILL MAKE UP FOR THE GAIN UNIT PART OF THE PROPOSED E-LED AND ENGINEERING OF GAIN TO DIFFRACTION RATIO WILL BE THE MAIN TOOL TO OPTIMIZE THE DIFFERENT DESIRE SPECS SIMULTANEOUSLY.
