Photoelectronic technology is closely related to electronic technology. Electronics is a science and technology with application as
its main purpose. It mainly studies the characteristics and behavior
of electronics and the physics of electronic devices. Electronics
involves many scientific categories, including physics, chemistry,
mathematics, materials science and so on. Photoelectronics refers
to the electronics of light wave bands, namely infrared, visible,
ultraviolet and soft X-ray (wavelength range 1–10 nm). It is a science
that studies photons as information carriers and energy carriers. It
mainly studies how photons produce, move and transform. Electronic technology is a technology that studies the motion law of
electrons and is applied to electronic devices, circuits and equipment. Photoelectronics technology is a technology that studies the
interaction between light and electricity, that is, photons or light
waves and electrons. It includes photoelectronics energy technology
and photoelectronics information technology. Photoelectronics technology is inseparable from electronic technology. Photoelectronics
technology needs energy–light conversion, light source needs driving
and control circuit to emit light, and photoelectric signal processing
is needed in the information field. At present, a large number of
information processing is still based on electronic technology, and
the conversion and amplification between electrical information and
optical information are still needed in the process of transmitting and
receiving. The core of future information technology is optoelectronic
technology. The advantages of optoelectronic technology in the
field of information technology are embodied in the following three
aspects.
