A microwave antenna array with injection locked quantum dot laser sources

The combining of power of multiple quantum dot mode locked lasers functioning as microwave sources is studied in detail. By injection locking two or more of these devices together, the lasers can feed different elements of the same antenna array radiating at a single frequency. The procedure to determine the injection locking properties of the lasers as microwave sources and to use these lasers to feed a microwave antenna arrays is discussed.
