ABSTRACT:
A phased array with several optical waveguides with optical lengths that increase from waveguide to waveguide has a first arrangement for modifying the optical length of waveguides with the modification increasing from waveguide to waveguide in one direction and a second arrangement for producing a modification of the optical length with the modification decreasing from waveguide to waveguide in the one direction.
