Abstract
An optical device includes first and second optical branches. The first optical branch is formed at an interface between a first substrate and a second substrate, and the second optical branch is formed at an interface between the second substrate and an ambient medium. The second substrate defines first and second spaced apart slits that are each coupled to the first and second optical branches. The first slit is configured to receive at least partially coherent light from a light source and in response excite at least one surface plasmon polariton mode in each of the first and second optical branches. The second slit is configured to combine the surface plasmon polariton modes received from the first and second optical branches and emit scattered light into at least one of the first substrate and the ambient medium.
