摘要: A chirped grating focuses guided waves to variable space points as determined by the intensity of a control beam. This can be achieved with light controlled spatial scanner which includes corrugated waveguide fabricated material having non-linear index coefficient refraction n 2 . The has corrugations period that varies linearly from Λ(O) at one point Λ(L) another point, where is greater than Λ(L). Guided modes are applied within in direction other wherein couple radiation focused focal spot space. varied cause traverse path without waveguide, dependent upon intensity.
