PM Combiner

PM Combiner is an optical device used to combine multiple polarized light signals into a single output signal while maintaining its polarization state. It usually consists of a polarizing beam splitter or polarizing coupler. The main function is to combine multiple polarized light signals into one output signal while keeping the polarization state of the combined output light consistent with the polarization state of the input light. This means that the polarization direction of the combined output optical signal is the same as that of the input optical signal.

The specific structure of PM Combiner can vary according to different design requirements and application scenarios. One common design uses a polarizing beam splitter. A polarization beam splitter can split the input polarized light signal into two branches and then recombine them into a single output signal through appropriate optical design. During this process, the polarization beam splitter can maintain the polarization state of the optical signal and ensure that the combined output optical signal and the input optical signal are consistent in the polarization direction.

Realize laser array: PM Combiner can combine the output optical signals of multiple lasers into one optical fiber to realize laser array. Laser arrays offer higher power and beam quality for a variety of applications, including lidar, optical communications and fiber optic sensors.

Beam shaping of fiber laser systems: By combining the output optical signals of multiple lasers, beam shaping and control can be achieved, such as wavefront merging and beam shaping. This helps optimize the power distribution and beam characteristics of the laser system.

Fiber Bragg Grating Sensors: PM Combiner can be used to combine the reflected light signals of multiple fiber Bragg grating sensors to increase the sensitivity and coverage of the sensor network. This is very beneficial for fiber Bragg grating sensor applications in areas such as structural monitoring, temperature measurement and strain measurement.

Fiber optic sensor array: By merging the signals of multiple fiber optic sensors, higher signal collection and transmission efficiency can be achieved, improving the overall performance of the sensor array. This is of great significance for the application of fiber optic sensors in fields such as environmental monitoring, biosensing, and industrial control.
