Crosstalk can be reduced in optical waveguide bundles(110) by varying the widths of individual waveguides(111-161). Using different width waveguides reduces the growth of crosstalk between the optical waveguides, thereby allowing the waveguides to be placed in closer proximity to increase waveguide density on the chip(200) and/or reduce the routing space required for the waveguide bundle(110). Moreover, varying the width of a waveguide spiral may reduce crosstalk, which can increase power efficiency when implemented in coiled or folded waveguide thermal optical (TO) devices. |
