Abstract

A planar light circuit comprises a substrate and a first pixel. The first pixel comprises a first number N of laser diodes, a first waveguide located on the substrate, a first number N of inlets which couple the first number N of laser diodes to the first waveguide and a first outlet. The first waveguide couples the first number N of inlets to the first outlet.An arrangement comprises the planar light circuit. The arrangement is realized as data glasses.
