An optical isolator, or optical diode, is an optical component which allows the transmission of light in only one direction. It is typically used to prevent unwanted feedback into an optical oscillator, such as a laser cavity. The operation of the devices depends on the Faraday Effect (which in turn is produced by magneto-optic effect), which is used in the main component, the Faraday rotator. In electronics, an opto-isolator, also called an optocoupler, photocoupler, or optical isolator, is a component that transfers electrical signals between two isolated circuits by using light. Opto-isolators prevent high voltages from affecting the system receiving the signal.[2] Commercially available opto-isolators withstand input-to-output voltages up to 10 kV[3] and voltage transients with speeds up to 10 kV/μs. A common type of opto-isolator consists of an LED and a phototransistor in the same opaque package. Other types of source-sensor combinations include LED-photodiode, LED-LASCR, and lamp-photoresistor pairs. Usually opto-isolators transfer digital (on-off) signals, but some techniques allow them to be used with analog signals.
Technological innovation drives performance upgrades
Breakthroughs in on-chip integration and miniaturization: New integrated optical isolators based on silicon-based photonics have become the focus of research and development. By combining magneto-optical materials (such as Ce:YIG) with CMOS processes, the device size can be reduced to less than 1 cm3, while the isolation degree can be increased to >40 dB.
Material and process innovation: The application of third-generation semiconductors (such as gallium nitride) has enhanced the high-temperature resistance and high-frequency performance of isolators, making them suitable for high-voltage electronic control scenarios in new energy vehicles. New non-magnetic optical isolation technologies (such as nonlinear optical effects) break through the limitations of magnetic field dependence, reducing the complexity and cost of devices.
Diversified expansion of application scenarios
The penetration in emerging fields is accelerating: The demand for isolators in photovoltaic inverters and energy storage systems has soared, and the devices need to meet the requirements of a withstand voltage of over 1500V and EMC anti-interference. 5G/6G communication and data centers: The proportion of isolators in 25G/100G optical modules has increased to 15%, and high-speed isolators (>1Gbps) have become standard equipment for optical communication.
The intelligent demand for high-end manufacturing: The servo system of industrial robots adopts photoelectric isolators to achieve precise signal transmission, and the synchronization accuracy requirement reaches +-0.1μs. Isolators in medical devices (such as MRI) are used to block common-mode interference, and the isolation voltage standard has been upgraded to 10kVrms.
