7、 Development history:

Silicon photodiode is a photoelectric conversion device based on silicon materials, which can convert light energy into electrical energy. Its development process can be traced back to the 1950s.

In the early 1950s, the application of silicon photodiodes was limited due to the low photoelectric conversion efficiency of silicon materials. However, with the development of semiconductor technology, the preparation process of silicon materials has gradually improved, and the performance of silicon photodiodes has also been improved.diode

In 1962, American physicists Eugene W. Mueller and Glenn H. Wright first achieved the detection of silicon photodiodes in the frequency band of 1.1 THz.diode

In the 1970s, with the rapid development of microelectronics technology, the manufacturing cost of silicon photodiodes gradually decreased and their performance gradually improved. This has enabled silicon photodiodes to be widely used in fields such as communication and optoelectronic sensing.diode

In the 1990s, with the rise of optical communication technology, silicon photodiodes were widely used in optical communication systems. Due to the high photoelectric conversion efficiency of silicon materials, silicon photodiodes can achieve high-speed and high-sensitivity photoelectric conversion, becoming important receiving devices in optical communication systems.diode

In recent years, with the development of nanotechnology, silicon photodiodes have also received attention in the field of nanophotonics. People have further improved the performance of silicon photodiodes by introducing nanostructures or quantum effects, achieving higher detection sensitivity and lower noise levels.diode

Silicon photodiodes have gone through a development process from initial preparation difficulties and poor performance, to later cost reduction and performance improvement. With the advancement of technology and the increasing demand for applications, silicon photodiodes have broad prospects for application in fields such as optical communication and optoelectronic sensing.diode
