A current-injection organic semiconductor laser diode comprising a pair of electrodes, an optical resonator structure, and one or more organic layers including a light amplification layer composed of an organic semiconductor, which has a sufficient overlap between the distribution of exciton density and the electric field intensity distribution of the resonant optical mode during current injection to emit laser light.
A method for designing a current-injection organic semiconductor laser diode, comprising:
- selecting materials and designing structure of the diode so as to increase the overlap between the distribution of exciton density and the electric field intensity distribution of the resonant optical mode during current injection.
A method for producing a current-injection organic semiconductor laser diode, comprising:
- evaluating the overlap between the exciton density distribution and the electric field intensity distribution of the resonant optical mode during current injection in a designed or existing diode,
- changing at least one of the materials and the structure of the diode to so design a new diode as to increase the overlap between the distribution of exciton density and the electric field intensity distribution of the resonant optical mode during current injection, and
- producing the new diode.
A program for designing current-injection organic semiconductor laser diode, which designs a current-injection organic semiconductor laser diode to increase the overlap between the distribution of exciton density and the electric field intensity distribution of the resonant optical mode during current injection.
