Effect of annealing treatment on the refractive index change is observed in fluorinated rigid and semi-flexible chain polyimide film waveguide. The experimental results show that before the completion of thermal imidization, the refractive index change increases rapidly with the annealing temperature and displays a large positive average thermo-optic coefficient. However, after the thermal imidization...
Two-dimensional coupled photonic crystals waveguides (CPCWs) constructed with a portion of 12-fold photonic quasicrystals are studied. Finite-difference time-domain is performed to investigate the properties of light propagating through the waveguides, and shows that reduced group velocity and flexible waveguide modes can be obtained in such CPCW structures. Our results verify a feasible way for constructing...
Compared with As20S80, P2As20S78 film waveguide deteriorates the response behavior of recovery propagation and mainly performs the slow later stage in recovery propagation process. However, for Sn1As20S79, it can improve evidently the fast earlier stage in the recovery propagation process to shorten response time to the milliseconds level, and also reduce the optical propagation loss. Experiments...
