OPTICAL PHASED ARRAYS |
摘要 |
OPTICAL PHASED ARRAYS Optical phased arrays employing a large number of light emitters and optical phase delays between adjacent emitters to steer and focus an optical beam from the contributions of all the light emitters. The array can include a laser oscillator (22) as the light source, with the laser light being conducted via optical waveguides (26, 30 and 32) into optical fibers (34), with phase delays being effected by piezoelectric or electro-optic effects on the optical waveguides. The array can be used in a low cost display device for generating optical images or in an optical memory.
