<p>The invention provides a method for fabricating an optical device comprising at least one optical component formed on a transparent substrate. The method comprises determining an area of the substrate that is to be light -absorbing; and fabricating a light-absorbing mask on the determined area prior to fabricating the at least one optical component. The invention also provides an optical device comprising a substrate (102); and first and second optical components formed on the substrate, wherein the first optical component (104) has two modes, each mode producing a different optical response to light incident thereupon, and wherein the second optical component (108) absorbs light and is formed on the substrate before the first optical component is formed.</p> |
