An optical element and a method capable of electromagnetically inducing transparency in a solid. The optical element includes a solid having a number N of sites characterized by at least three energy levels including a first level higher than a second and a third lower than the second, and an excitation device configured to irradiate the solid with a first light having a wavelength corresponding to the energy difference between the first and the second level, and a second light having a wavelength corresponding to the energy difference between the first and the third level. The solid satisfies .sigma..sub.23 .ltoreq..sigma..sub.12 and .sigma..sub.23 .ltoreq..sigma..sub.13 where .sigma..sub.12, .sigma..sub.13 and .sigma..sub.23 are respectively the standard deviations of the energy differences between the first and second level, between the first and third level, and between the second and third level.

A method of forming an organic thin film includes developing organic molecules having a hydrophilic portion and a hydrophobic portion on a water surface, and compressing the organic molecules thereby to form a monomolecular layer of a predetermined surface pressure. The monomolecular layer is brought into contact with a given substrate. Then, the substrate to which the monomolecular layer is adhered, is pulled at such a rate that the surface pressure is not substantially lowered, thus transferring the monomolecular layer onto the substrate.

An organic thin film display element comprises an organic thin film containing donor moleculaes and acceptor molecules and a pulse voltage source for causing a charge transfer between the donor molecules and the acceptor molecules. The charge transfer varies the optical characteristic of the organic thin film, whereby the organic thin film displays an image.

摘要:
This invention is characterized in that information is recorded by injecting electric charge into a charge holding region made from a donor or acceptor, and the recorded information is reproduced by using changes in luminescence characteristics of the luminescent material contained in the charge holding region or a light emitting region formed near the charge holding region, that occur in accordance with the charge condition of the charge holding region.

Two mirrors comprising a resonator, arranged facing to each other interpose an EIT layer, which is a solid containing an impurity. A controlling light from a controlling light source and a pumping light from a pumping light source enter the EIT layer. A photodiode detects the intensity of an LWI laser light (a signal light outputted from the EIT layer) outputted from one of the mirrors. A filter for cutting the controlling light is provided between the photodiode and the mirror. Two kinds of lights, that is, the controlling light and the pumping light are used in all the .LAMBDA., V, .XI. type three levels. In the .LAMBDA. type three levels, the controlling light is used for supposedly exciting between the levels, and the pumping light is used for pumping electrons from the level to the level via the level. In the V type three levels, the controlling light is used for exciting between the levels, and the pumping light is used for pumping electrons from the level to the level via the level. In the .XI. type three levels, the controlling light is used for supposedly exciting between the levels, and the pumping light is used for pumping electrons from the level to the level via the level.
摘要:
A method of recording information in an optical recording medium, which comprises two steps. In the first step, a coherent light pulse train which resonates with a transition between the first and third energy levels and coherent light which resonates with a transition between the second and third energy levels or a transition between the first and second energy levels are applied to the optical recording medium, thereby causing the light pulse train to pass through the optical recording medium. In the second step, an intensity change of an external field is supplied to the medium, while the light pulse train is passing through the optical recording medium, thereby fixing sites in a thickness direction of the medium, at which the absorption spectrum of the medium is changed.
