Optical phased array device and method of manufacture

A method of manufacturing an optical phased array for an optical phased array device, comprising:

• forming a base layer of a waveguide array on a base substrate;
• determining a waveguide pattern defining a plurality of waveguide paths, wherein the plurality of waveguide paths branch from a common path and terminate at a plurality of edge emitters, wherein the plurality of edge emitters are spaced apart from one another along a first axis, wherein the first axis extends in a first dimension along an edge of the optical phased array, wherein spacing of two or more of the plurality of emitters along the first axis is aperiodic, wherein the spacing of the two or more of the plurality of edge emitters is determined based on an aperiodic constant that varies according to a recursive function that incorporates the aperiodic constant for an adjacent edge emitter, and wherein the plurality of waveguide paths include an omega shaped phase delay configuration;
• and
• fabricating a pattern layer of the waveguide array on top of the base layer of the waveguide array according to the determined waveguide pattern.
