Abstract:
A semiconductor optical device has a multilayer structure  30  including a first compound semiconductor layer  31 , an active layer  33 , and a second compound semiconductor layer  32 . A second electrode  42  is formed on the second compound semiconductor layer  32  through a contact layer  34 . The contact layer  34  has a thickness of four or less atomic layers. When an interface between the contact layer  34  and the second compound semiconductor layer  32  is an xy-plane, a lattice constant along an x-axis of crystals constituting an interface layer  32 A which is a part of the second compound semiconductor layer in contact with the contact layer  34  is x 2 , a lattice constant along a z-axis is z 2 , a length along an x-axis in one unit of crystals constituting the contact layer  34  is x c ′, and a length along the z-axis is z c ′, (z c ′/x c ′)>(z 2 /x 2 ) is satisfied.

Claim (Index 10):
The semiconductor optical device according to  claim 1 , wherein the first conductivity type is n-type, and the second conductivity type is p-type.
