Imprinted conjugated polymer DFB lasers optimized based on simulation results
Source abstract
Abstract
In this study, we present distributed feedback structure lasers which were fabricated by imprinting a grating directly into a highly luminescent conjugated polymer. Based on the interplay between simulations and experimental results, we optimized some basic parameters, crucial for the effective behavior of the structure. On the base of these parameters, new grating structures were designed and fabricated by e-beam lithography and transferred to the polymer by the soft lithographic technique of “liquid imprinting”. Due to these improved grating structures, the devices showed stable, low threshold lasing under photo-excitation using a frequency doubled Nd:YAG laser. The obtained experimental results were again successfully modeled by simulating the electromagnetic modes within the structure, and, in addition, the grating response to an electromagnetic field as a function of the waveguide thickness and grating depth was monitored.
