Fabrication of graded index waveguides in azo polymers using a direct writing technique
Hamidreza KarimiAlavijeh, Gholam-Mohammad Parsanasab, Mohammad-Amin Baghban, Edris Sarailou, Alireza Gharavi et al.
Fast direct writing of waveguides on polymers using low power continuous-wave lasers has been investigated. Using the cis-trans property of a functionalized sulfonated azo chromophores, we have fabricated graded index waveguides with low loss, which is due to graded index sidewalls. Fabrication is d … [Appl. Phys. Lett. 92, 041105 (2008)] published Mon Jan 28, 2008.
