Abstract :
A tunable polarization diversity silicon waveguide based optical filter with fiber assembly was demonstrated. With the polarization diversity scheme, polarization dependent loss (PDL) being less than 0.5 dB was achieved in the silicon optical filter. The insertion loss of the packaged polarization diversity module is ~13.4 dB. The extinction ratio of the optical filter is about 20 dB, and the tuning range is ~11.7 nm, along with the 3dB bandwidth of 0.2 nm.
