Abstract

Dendrimer is a workhorse nanomaterial for a number of important photonic devices. The electro-optic (EO) properties of a chromophore doped and poled dendrimer film exhibits higher electro-optic coefficient ^r33 . Measured refractive index shows significant difference between poled and unpoled dendrimer film. The ^r33 value was determined to be ~130 pm/V at 633 nm that dropped to ~90 pm/V at 1553 nm. Dendrimer waveguide can be used to design several important photonic devices. EO dendrimer is used to generate terahertz radiation via electro-optic route. Here electro-optic rectification and difference frequency generation has been demonstrated. Significantly higher terahertz power can be generated by the higher χ⁽²⁾ dendrimer emitter of the present investigation.
