Abstract: The disclosure pertains to methods for modifying empathy in a subject, such as a human, by modulating type 2 theta oscillations in a brain region of the subject. The methods include increasing empathy in a subject, such as a human, by increasing type 2 theta oscillations in a brain region of the subject, thereby increasing empathy in the subject. The human subject may have a psychiatric or neurological condition that causes suboptimal empathy. Modulating type 2 theta oscillations in a brain region of a subject can be accomplished by optogenetic treatment, electric stimulation of a brain region, administration of a pharmaceutical drug, or a combination thereof. Also provided are systems for performing the methods disclosed herein.

Abstract: A wavelength multiplexing device is disclosed. When light is irradiated on a first longitudinal end region of a metal nano-structure, surface plasmon polaritons are generated in the first longitudinal end region. The surface plasmon polaritons and the light are coupled with each other to form first coupled surface plasmon polaritons, wherein the first coupled surface plasmon polaritons propagate along and on a surface of the metal nano-structure. When the first coupled surface plasmon polaritons reach a two-dimensional material layer, excitons are induced in the two-dimensional material layer, wherein the induced excitons and the first coupled surface plasmon polaritons are coupled with each other to form second coupled surface plasmon polaritons. The second coupled surface plasmon polaritons propagate along and on a surface of the metal nano-structure toward a second longitudinal end thereof.
