Latest Patents
Among Yongqiang Shi's most recent patents is a remarkable invention regarding **optical depolarizers and differential group delay (DGD) generators based on optical delay**. This technology allows for the depolarization of light and the creation of variable differential group delays in optical signals. The process involves splitting an input optical beam into two beams with orthogonal polarizations, which are then altered through different optical path lengths using reflectors before being recombined. An adjustment mechanism can fine-tune these path lengths to achieve the desired DGD. Importantly, when light depolarization is necessary, the path length difference is strategically set to exceed the coherence length of the input beam.
