Method for operating a phased array

摘要

The optical coupling arrangement includes at least one pair of adjacent strip-shaped optical waveguide endings for coupling in optical radiation. The ends are a small distance apart. The waveguide endings each have an optical longitudinal axis arranged at an angle alpha w.r.t. each other. The angle alpha is less than the aperture angle at the end of the waveguide endings. Alpha is e.g. less than 2 degrees. The ends of the waveguide sections are coupled to the front surface of a layer waveguide or to an optical phased array at a specific wavelength. This wavelength is used as a reference wavelength for stabilisation.
