Abstract

<abstract abstract-type="graphical" xml:lang="en" id="lpor201400078-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p>A waveguide‐based ultra‐broadband mode‐multiplexer, fabricated using the femtosecond laser direct‐write technique, is presented. The three‐core coupler is shown to enable the multiplexing of the LP₀₁, LP_11a and LP_11b spatial modes of a multimode waveguide, across an extremely wide bandwidth exceeding 400 nm, with low loss, high mode‐extinction ratios and negligible mode crosstalk. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgh1302256j" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
