Near-infrared luminescent polymer amplifiers and microlasers
Djiango, Martin Nkrumah (Trinity College (Dublin, Ireland). School of Physics, 2008)Near-infrared optical gain in luminescent polymeric slab asymmetric waveguides has been investigated by use of amplified spontaneous emission. Upon nanosecond photopumping, the waveguides have shown a small-signal gain ...
