ABSTRACT:
The laser device has a gain medium, first and second clads sandwiching the gain medium in the thickness direction, and a cavity structure for resonating the electromagnetic wave generated in the gain medium. The gain medium includes a plurality of active regions for generating an electromagnetic wave and at lease one connecting region sandwiched among the active regions. The first and second clads are each formed of a negative permittivity medium having a permittivity the real part of which is negative relative to the electromagnetic wave. A potential-adjusting portion is arranged between the connecting region and the first clad and between the connecting region and the second clad for adjusting the electric potential of the connecting region.
