Small-sized, ultra-low phase noise photonic microwave oscillators at X-Ka bands


Small-sized, ultra-low phase noise photonic microwave oscillators at 10, 20, 30, and 40 GHz are demonstrated using electro-optical frequency division. At 40 GHz, a record-low, to our knowledge, phase noise of −153 dBc/Hz is achieved (10 kHz offset).
