Internally sensed optical phased array

Bowman, David J; King, Malcolm J; Sutton, Andrew J; Wuchenich, Danielle M; Ward, Robert L; Malikides, Emmanuel A; McClelland, David E; Shaddock, Daniel A


Extending phased array techniques to optical frequencies is challenging because of the considerably smaller wavelengths and the difficulty of stabilizing the optical path lengths of multiple emitters to this level of precision. This is especially true under real-world conditions where thermal and vibrational disturbances cause path length variations that are considerable in relation to the wavelength. Earlier attempts have relied on an external mechanism to sense and compensate for any unwanted...[Show more]
