Claim 0:
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,
wherein the one or more organic layers are laminated on the surface of the substrate so that one of the one or more organic layers contacts with the first electrode, and
at least one of the following conditions is satisfied:, (A) the optical resonator structure has a grating with a gap at least in a part on the side facing the first electrode,, (B) the optical resonator structure has a grating having a completely-removed groove,, (C) the optical resonator structure has a grating having a groove in which the first electrode is exposed,, (D) the optical cavity structure has a grating having a plurality of insulating layers periodically arranged on the surface of the first electrode, and, (E) the optical cavity structure has a grating pattern formed directly on the surface of the first electrode.
