We report a method for compensating the birefringence of optical polymers by doping them with inorganic birefringent crystals. In this method, an inorganic birefringent material is chosen that has the opposite birefringence to that of the polymer and has rod-shaped crystals that are oriented when the polymer chains are oriented. The birefringence of the polymer is thus compensated by the opposing birefringence of the crystal. Birefringence is minimized in various polymer optical devices by adjusting process conditions, because it degrades the performance of devices. This method minimizes it, independent of process conditions, which potentially improves the productivity of devices.
我们报告了一种通过向光学聚合物中掺杂无机双折射晶体来补偿其双折射的方法。在该方法中，选择一种无机双折射材料，其双折射与聚合物的双折射相反，并且具有棒状晶体，当聚合物链取向时这些晶体也会取向。聚合物的双折射因此被晶体相反的双折射所补偿。在各种聚合物光学器件中，通过调整工艺条件可使双折射最小化，因为双折射会降低器件的性能。该方法可使其独立于工艺条件而最小化，这有可能提高器件的生产率。
