Electro-optic phenomena in gelatin-based poled polymer

An electro-optic polymer with nitrophenol and photo lime gel has been constructed and demonstrated. The transmission spectrum of nitrophenol/gelatin shows an ultrawide optical bandwidth, from 340 to 2800 nm. A relatively stable and large electro-optic effect, γ33=10–40 pm/V, was observed at 632.8 nm. The poling stability is attributed to the two-dimensional cross-linked nature of the gelatin. This result indicates that both passive and active integrated optical devices can be fabricated onto the same polymer thin film to form a fully polymer-based miniature integrated optical circuit.
