OG exemplary drawing
 
1. A current-injection organic semiconductor laser diode comprising:
a substrate composed of a first electrode and an optical resonator structure of an insulating material,
one or more organic layers including a light amplification layer composed of an organic semiconductor, and
a second electrode,
which has a sufficient overlap between a distribution of exciton density and an electric field intensity distribution of a resonant optical mode during current injection to emit laser light,
wherein the organic layers are laminated on the surface of the substrate.
