Abstract
Summary form only given. We demonstrate an evanescent field coupler by selective heat-treating a region of a previously uncoupled twin core PCF. The twin-core PCF presented in this paper was fabricated, as described previously, with the two cores separated by four capillaries. The capillaries between the two cores were thicker walled than those in the rest of the stack so that the air holes between the cores would be smaller.
