An Experimental Research About Dye-Doped Distributed Feedback Laser

Dye-doped distributed feedback (DFB) structure is an essential structure for DFB laser. This paper presents an operative method to design a kind of dye-doped distributed feedback laser based on dye-doped holographic polymer dispersed liquid crystal (HPDLC) matrix. The results show that we have processed DFB structure of 10 mu m period, with a relatively low period deviation of less than 1%. Furthermore, we gain output characteristics of DFB structure through experimental methods, which show good characteristics for wide tuning range, narrow linewidth laser output production.
