It is more extensive, to the demand of polarization maintaining optical fibre array also rapid growth.Because polarization maintaining optical fibre array needs and chip of light waveguide or micro-
Lens array butt coupling, the fibre core of polarization maintaining optical fibre array is away from must have very high precision, while its crucial optical parametric disappears
Light ratio be also required to it is sufficiently high so that polarised light of its transmission keeps stable.
Polarization maintaining optical fibre array is by a kind of more polarization maintaining optical fibres accurately optical fibre device of parallel arranged together, extinction ratio
It is the key parameter of polarization maintaining optical fibre array, it directly affects the using effect of polarization maintaining optical fibre array, thus requires these polarization-maintaining light
Fine polarization axis direction has the uniformity of height.
Therefore, it is necessary to be rotated to every polarization maintaining optical fibre, so that it is polarized in the preparation process of polarization maintaining optical fibre array
Axle is in direction vertically or horizontally, and existing method is that polarization maintaining optical fibre end face is put by microscope or CCD monitors
Big observation, it is artificial whether to judge polarization maintaining optical fibre polarization axle in direction vertically or horizontally, because of judgement of the eyes to angle of people
Have larger error, it will usually there is 3 degree of angular deviation, and for more polarization maintaining optical fibres, it is understood that there may be clockwise direction deviation
Or counter clockwise direction deviation, then on the whole maximum just has 6 degree of deviation.With the port number (fiber count of polarization maintaining optical fibre array
Amount) it is higher, the probability that large deviation occurs in artificial judgment is higher, so polarization maintaining optical fibre array in the market, its port number is got over
Greatly, its polarised light parameter index can be deteriorated.
In summary, polarization axle control of the existing polarization maintaining optical fibre array production equipment to polarization maintaining optical fibre is not accurate enough
, substantially judge by human eye.
