Abstract

An integrated photonics arrayed waveguide multiplexing/demultiplexing device (1) comprising:- an array (30) of waveguides (300) comprising:o an incident light waveguide section (301) comprising a phase correcting region (31);o a transmitted light waveguide section (302);o a tunable reflector (32);wherein each pair of consecutive waveguides (300) in the array (30) comprises a coupler (33) configured to:- combine light from the transmitted light waveguide sections (302);- determine therefrom an optical phase difference between the two consecutive waveguides (300); andwherein the couplers (33) are further configured to determine therefrom a change (3) in optical path length required for each of two consecutive waveguides (300) to reach a predetermined optical phase difference;and wherein each phase correcting region (31) is configured to apply the change (3) to correct the optical path length of the respective waveguide (300).
