Optical isolator is a passive optical device that only allows one-way light to pass through. Its working principle is based on the non-reciprocity of Faraday rotation, with the main function of preventing the adverse effects of backward transmitted light on the light source and optical system due to various reasons in the optical path. In coherent optical long distance optical fiber communication systems, an optical isolator is installed at intervals to reduce the power loss caused by stimulated Brillouin scattering. Therefore, optical isolators play an important role in optical fiber communication, optical information processing systems, optical fiber sensing and precision optical measurement systems.
According to different optical isolator technologies used, optical isolators can usually be divided into two categories: polarization-dependent optical isolators and polarization-independent optical isolators. Polarization-dependent optical isolators require the forward input light to be linearly polarized light, and the polarization direction is fixed. Such isolators are usually composed of an input bias element, a Faraday rotator and an output bias detection element, and the reflected light is usually absorbed or reflected by the bias or bias detection element, so as to achieve the purpose of isolating the reflected light; The polarization-independent optical isolator does not limit the polarization state of the input light, allowing the forward light of any polarization state to pass without loss, while making the reflected light deviate from the forward light path and cannot enter the active optical chip, so as to achieve the purpose of isolating the reflected light.
According to our research data, the total global optical isolator market revenue is expected to reach $587 million in 2023, among which the market revenue of polarization-dependent optical isolators is estimated to reach $124 million, accounting for 21.12%; Polarization-independent optical isolator market revenue is estimated at $463 million, with a market share of 78.88%.

Modern electronic system is the theme of today’s
era. Various applications such as industrial automation, telecom base station
power supplies and on-board chargers for electric vehicles require the support
of electronic systems to develop better and more stably. The challenges faced
by modern electronic systems, such as how to protect the safety of electronic
control devices and operators, how to effectively communicate between
subsystems with high potential differences, and how to prevent the destruction
of sensitive signals by electrical noise, can all be solved by using optical
isolators. Optical isolators allow multiple power domains to coexist and
communicate, where sensitive circuits and switching circuits are isolated. As a
result, both performance and component security are improved in many cases. To
sum up, the role and value of optical isolators in the system is an important
intrinsic driving force for market growth and industry development.
