Design of a Tunable Broadband Conjugated-Polymer Laser in Solution

Abstract—In this work, we had shown that the conjugated-polymer poly(9,9-dioctylfluorenyl-2,7-diyl) (PFO) in benzene can produce amplified spontaneous emission (ASE) with tunablity more than 100 nm from 410nm to 510 nm. And then we had shown that the conjugated polymer poly [2-methoxy-5-(2-ethylhexyloxy)-1, 4-phenylenevinylene] (MEH-PPV) in benzene could produce ASE and lasing from 550 to 650 nm. Finally, we added appropriate molar concentration of these conjugated polymers in benzene to form a solution which has highest optical gain for each conjugated polymer individually. The results showed that these conjugated polymers could lase individually as well as by an energy transfer process from one conjugated polymer to another in tandem.

Index Terms—Tunable laser, conjugated polymer, broadband, amplified spontaneous emission (ASE).
