Plant device.Optoisolator can be divided into polarization relationship type by it to the degree of dependence of transmission optical polarization
And polarization independent type.No matter the feature of polarization relationship type is to input the polarization state of light wave, warp
The light wave crossing its output all determines the line polarized light of polarization direction by becoming to have, so defeated for being unsatisfactory for
The transmission light entering polarization state requirement all will be attenuated the light intensity of half, reduce the application of transmission light wave
Efficiency.The feature of polarization independent type is that transmitting light is divided into two bundle polarized light, then in optoisolator
By rotatory polarization state, more again couple, remove light beam in transmitting procedure at each optical element
Outside the inevitably decay that reflection and scattering produce, the most do not produce other losses.Reality
Application need more optical device insensitive to the polarization state of transmission light wave, in order to adapt under multiple occasion
The requirement of system.Existing than more typical polarization independent type, the light that utilizes bulk crystals to realize function
In isolator, be divided into single-stage isolated device and Double-stage isolator according to the feature of its isolation structure, twin-stage every
Isolation from device is greater than single-stage, but insertion loss is also big, and owing to using crystal element quantity
More than single step arrangement, therefore on cost, will be higher in technology difficulty.
