dc.description.abstract | A simple approach to producing tunable lasing is explored. In this work, a basic planar lasing system with a layer of light emitting conjugated polymer, MEH-PPV, sandwiched between a distributed Bragg reflector (DBR) and silver is utilized. By irradiating MEH-PPV with electrons, the photoluminescence (PL) spectrum of MEH-PPV undergoes blueshift and peak broadening, which in turn alters the lasing wavelength. Furthermore, patterning the MEH-PPV layer by electron irradiation and employing filters allow lasing to be controlled to occur only at certain areas. Thus, our approach allows the fabricated system to possess significant tunability, a highly sought out trait in the field of lasing. The detailed methodology by which tunable lasing is achieved is discussed along with the mechanism behind the irradiation-induced blueshift of the PL spectrum. | - |
