Title:
DENSELY-PACKED OPTICAL PHASED ARRAYS VIA K-VECTOR MISMATCH AND METAMATERIAL RODS
Document Type and Number:
WIPO Patent Application WO/2019/190577
Kind Code:
A3
Abstract:
A method of forming an emitting array of waveguides, comprising providing a plurality of waveguides that exhibit different propagation constants so as to ensure that nearby waveguides do not couple evenly over parallel propagation lengths by varying a length in one or more dimensions of respective waveguides, whereby the respective waveguides are phasemismatched with at least their nearest neighbor.
