Abstract, Apparatus according to the invention comprises an optical or opto-, electronic device that comprises one or more "trapping" layers that can speed the decay of a non-equilibrium carrier distribution in an active region of the device thereby improving device characteristics. In preferred embodiments the trapping layers are arranged so as to increase the likelihood of radiative recombination of carriers leading to eased heat sinking requirements.
