TRANSMITTER AND COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a transmitter and a communication system capable of enhancing a transfer rate of data.

SOLUTION: An LED element 10, as a transmitter, comprises a light emitting section 130 and a plurality of modulating sections 120. The modulating sections 120 each include a modulation electrode layer 106 and a moth-eye structure layer 105, each connected to a signal input power source 121. Voltage is applied to the modulation electrode layer 106 and an n-side electrode 103 to generate a changing electric field in a material of the moth-eye structure layer 105. The electric field changes a refractive index of the moth-eye structure layer 105 to modulate light from the light emitting section 130. The plurality of modulating sections 120 modulate light emitted from the same light emitting section 130 according to respective different signals.
