である。Nonlinear optical elements play an important role in the fields of optical communication and optical detailed processing. The non-linear optical material used in the non-linear optical element is a light mixture that generates a sum and a difference frequency of two types of incident light having different frequencies, an optical parametric in which these are irradiated as light having a frequency different from the original frequency, and , The Pockels effect or Kerr effect due to the change of the refractive index of the optical medium, or the conversion of incident light into the second harmonic (SHG) or the third harmonic (THG),
Furthermore, it is a substance that plays an extremely important role in optical signal processing, such as memory effect due to optical bistability. Conventionally, inorganic compounds have been mainly used as such nonlinear optical materials. Inorganic nonlinear optical materials include potassium phosphate titanate (KTP) (KTiOPO
4 ) and crystals of inorganic compounds such as lithium niobate (LN) (LiNbO 3 ) are known, but these have not sufficiently satisfied the requirements. on the other hand,
In recent years, organic non-linear optical materials have attracted attention as new optical element materials in the field of optoelectronics, and their research has been actively conducted. In particular, it is known that a compound having an electron-donating group and an electron-accepting group in a π-electron conjugated system exhibits strong optical nonlinearity at the molecular level due to the interaction between laser light as an electromagnetic wave and π-electrons unevenly distributed in the molecule. ing. The compounds that have been studied so far include 2-methyl-4-nitroaniline, m-nitroaniline, N- (4-nitrophenyl) -L-prolinol, 4-dimethylamino-4'-nitrostilbene,
4'-nitrobenzylidene-4-nitroaniline and the like can be mentioned. In addition, it is known that the cyclobutenedione structure bonded to the π-electron conjugated system functions as a strong electron-accepting group, and by utilizing such a structure, higher non-linearity than that of the conventional one is obtained. You have what you have. These materials, like the inorganic ones, are used in the single crystal state, but in these single crystals, 2
In order to exert the following non-linear optical effect, it is essential that the compound does not have central symmetry, but as a specific method for obtaining this, the introduction of asymmetric centers and the use of hydrogen bonds are useful. However, the current situation is that no general method has been found yet. Furthermore, due to the difficulty of crystal growth peculiar to organic substances, the fragility of the obtained crystals, and the difficulty of precision processing, it is the current situation that an element having high efficiency cannot be put into practical use.

げてしまうという大きな弊害がある。Recently, in order to overcome these drawbacks, an organic compound (optical nonlinear dye) having a high optical non-linearity is dispersed in a transparent amorphous polymer, and the mixture is mixed with the glass transition temperature of the amorphous polymer. As described above, a method has been developed in which a high electric field is applied while heating, the organic compound is oriented parallel to the electric field, and then cooled, and the orientation is fixed to obtain a material having no central symmetry. "Dye dispersion type electric field oriented polymer"
These materials, which are commonly referred to as, are characterized in that they have both optical non-linearity and workability due to the base polymer material. By utilizing this processability, the optical waveguide type device structure most promising as an optical information processing element can be easily realized. However, even in these electric field oriented polymers, the following points are limited in order to exhibit high optical nonlinearity. That is, first,
Since the obtained electric field oriented polymer is in a thermodynamically non-equilibrium state, there is a problem that the orientation of the optical non-linear dye is relaxed and the optical non-linearity of the material is deteriorated during long-term use. . This orientation relaxation process has a certain correlation with the glass transition temperature of the base polymer material (that is, the relaxation rate decreases as the polymer material with a higher glass transition temperature is used), but in general, the glass transition temperature decreases. It progresses rapidly at a temperature much lower than the temperature. Furthermore, in order to achieve high optical non-linearity, it is necessary to increase the concentration of the optical non-linear dye in the polymer material, but these dyes have a rigid structure with a developed π-electron conjugated system. Therefore, the solubility in polymer materials is not generally high. On the other hand, when the optical nonlinear dye is well compatible with the base polymer material, the nonlinear dye itself often acts as a plasticizer for the polymer material, and the glass transition temperature of the compatible material is lowered. There is a big evil that it ends up.

般に遅いとされている。In order to solve these problems, a "side chain type electric field oriented polymer" in which an optical non-linear dye is directly bonded to a side chain of a polymer has been proposed. The constraint on the concentration of the nonlinear dye is smaller than that of the dispersion type. In addition, the side-chain type electric field alignment monomer is generally said to relax the orientation of the optical nonlinear dye more slowly than the dispersion type.

い。Next, the polymer thin film formed as described above is oriented in an electric field. FIG. 4 is a schematic configuration diagram of a device for orienting an electric field, and this device is installed in a heating furnace. In the figure, 3 is a grounded plate electrode, 4 is an electric wire for applying a voltage, 5 is a power source, and a substrate 1 having a polymer thin film 2 formed thereon is placed on the plate electrode 3. As the flat plate electrode, a flat plate of copper is preferably used, but other metals such as silver having high conductivity and good thermal conductivity can be used. Also, as an electric wire for applying a voltage,
In addition to tungsten, a wire having a high heat resistance metal such as platinum, a high heat resistance alloy such as a platinum-iridium alloy, or a wire formed by plating these with an inert metal such as gold can be used. . The apparatus shown in FIG. 4 may be mounted on an apparatus having a structure in which only the flat plate electrode is temperature-controlled, instead of being installed in a heating furnace. Place the polymer thin film formed on the substrate on the grounded copper plate electrode and keep the temperature in the heating furnace at a temperature above the glass transition temperature of the homopolymer or copolymer that constitutes the thin film. Then, an appropriate voltage is applied to an electric wire installed with an appropriate distance from the copper plate electrode, and after holding for a certain period of time, heating is stopped and the system is allowed to cool. When the voltage is stopped after the temperature returns to room temperature, the polymer electric field oriented thin film is obtained. The applied voltage at that time is preferably in the range of 4 KV to 8 KV, and the heating time in the voltage applied state is preferably in the range of 1 minute to 30 minutes.
