Ultra-high-speed optical (signal) communication

Abstract

To provide a method that can contribute to achieving higher-speed optical communication, which is different from a conventional communication method using an optical signal, in which it has not been considered that higher-speed optical communication can be realized by using light which is faster than used visible light, because nothing can be transmitted faster than light.SOLUTION: Wave energy (a wave phenomenon) such as light (light waves) can be divided into transverse waves that oscillate in a direction perpendicular to a transmitting direction of waves and longitudinal waves that oscillate in a direction parallel to the transmitting direction of the waves. The longitudinal waves are higher in progressing (transmitting) speed than the transverse waves. Although the light (light waves) has been regarded as transverse waves, light (light waves) of longitudinal waves also can be generated. Higher-speed optical communication can be achieved by using the light (light waves) of the longitudinal waves.SELECTED DRAWING: None

Description

[Technical Field]

[0001] The present invention relates to an application technology of optical (signal) communication technology. [Background technology]

[0002] Communication technology (wired and wireless) using light (signals) Summary of the Invention [Problem to be solved by the invention]

[0003] Conventionally, communication methods using optical signals have used visible light, such as LEDs, as light sources. Because nothing travels faster than light, it was not recognized that different types of light can travel at different speeds, and so it was not even considered possible to realize faster optical (signal) communications using light, which travels faster than visible light. In response to this, we provide a method that differs from conventional methods and realizes optical (signal) communications at speeds higher than conventional optical (signal) communications. [Means for solving the problem]

[0004] Until now, it has been thought that light (light waves) are transverse waves (light (light waves) are limited to transverse waves), but this is not the case; it is also possible to generate longitudinal light (light waves). A longitudinal wave, also called a compressional wave, is a wave that vibrates in a direction parallel to the direction of wave propagation. Parallel waves (vibrations) are waves in which charged particles have areas of high density and areas of low density and travel (transmit) in a straight line. Longitudinal light (light waves) can be generated (transmitted) by using a phosphor as the light source and passing direct current (applying a direct current voltage) instead of alternating current. This method solves the problem.

Claims

1. The light (light waves) used in communication using optical signals is a type of wave energy (wave phenomenon) and is a phenomenon in which electrically charged particles vibrate. This light (light wave) is a transverse wave that travels through the air, and causes electrically charged particles present in the air to vibrate. (Light (light waves) is the vibration phenomenon of electrically charged particles.) A transverse wave is a wave that vibrates perpendicular to the direction of its travel. It vibrates in the perpendicular direction (a phenomenon in which it moves back and forth), and the distance between adjacent peaks and valleys in the repeating uneven shape is called the wavelength. The shorter the wavelength of this transverse wave (the higher the frequency of light (light waves)), the more directional (straight-line) the light (light waves) is, and therefore the faster it travels (transmits). Since nothing travels faster than light, we are not aware of the difference in speed within the same light, but since light is also wave energy (wave phenomenon), its speed varies depending on the direction of its vibration, its magnitude, and the length of its wavelength. (Even within visible light, red wavelength light and violet wavelength light travel at different speeds.) Even when communicating using optical signals, the communication speed varies depending on the type of light used. In the past, the difference in speed within the same light was not taken into consideration, so visible light (transverse waves) such as LEDs were used as the light source for optical signals. However, this method increases the speed of optical signal communication by using longitudinal waves of light instead of transverse waves such as visible light. A method of achieving faster communication speeds than conventional optical signal communications by using longitudinal wave light as the light source for optical signals. A longitudinal wave is a wave that vibrates parallel to the direction of its propagation. Also known as a compressional wave, it is a wave in which charged particles of a light wave travel (propagate) in a straight line, alternating between areas of high and low density in a direction parallel to the direction of the wave's propagation. In transverse waves, charged particles travel (propagate) repeatedly along uneven surfaces, while in longitudinal waves, charged particles travel (propagate) repeatedly along uneven surfaces with varying density. (Longitudinal light (light waves) are not visible light and are therefore invisible to the human eye, but they do function as optical signals.)
