“…It appears that there are two possibilities for the generation of such optical chirps. First, highly linear, broadband, stabilized frequency agile laser sources similar to those used in [15,[27][28][29][30][31][32] should be developed with frequency errors much smaller than the inverse of the optical chirp duration. Or, second, low-cost, highly linear, broadband rf swept sources should be developed and used in conjunction with next generation ϳ100 GHz bandwidth EOPMs such as those described in [37,38].…”
