摘要
The possibility to use electron-beam writing on an electro-optic cross-linkable polymer film deposited on a Si/SiO2 substrate is investigated. Both positive and negative electron-beam writings have been performed, with different exposure doses. Good resolution and a depth of 30 nm was obtained in the positive case, while in the negative case a lower resolution was obtained and a depth of 580 run. With negative writing we fabricated test channel waveguides of good optical quality.
