Nonlinear optical material and its method of manufacture

摘要

A new nonlinear organic optical material having a high Second Harmonic Generation capability and a method of manufacturing the same is disclosed. Energy-beam sensitive monomer molecules having large molecular dipole-moments are sandwiched between two facing orientation films formed on respective substrates, and the energy-beam sensitive parts in said molecules are polymerized by irradiation with an energy-beam such as an X-ray beam after the dipole-moments of the energy-beam sensitive monomer molecules are aligned by applying a magnetic or an electric field. As a result of this, no cancellation of dipole-moments takes place, and polymers having extremely high dipole-moments and high Second Harmonic Generation efficiency can be derived and manufactured.
