Silicon photonics
Technology for forming optical elements on silicon substrates. By using silicon, the optical circuits can be miniaturized, enabling larger scale concentrations. In addition, it offers features such as reduced manufacturing costs as well as unified formation of optical and electrical circuits.
A form of pulse amplitude modulation; a method that converts two bits of digital value (00, 01, 10, 11) to one pulse which has 4 levels of the voltage value, representing twice the information content of the previous technology, by controlling the pulse amplitude of 4 levels of the voltage value.
 Optical modulators
An element which converts an input electrical signal into an optical signal. It converts digital electric signals to digital optical signals by using the digital signal to change the refractive index of the light.
A thin-film patterning method. A pattern is formed on a substrate with a protective film called a resist. Then a layer of a substance such as metal is formed on top of it and the resist is dissolved, leaving a layer of metal only in places that were not covered by the resist, forming the desired pattern.

Following the two oil crises of the 1970s, the need for energy diversification increased. Against this backdrop, the New Energy and Industrial Technology Development Organization (NEDO) was established as a governmental organization in 1980 to promote the development and introduction of new energy technologies. Research and development of industrial technology was later added, and today NEDO is active in a wide variety of areas as one of the largest public research and development management organizations in Japan.
