Abstract: A semiconductor light emitting element includes an optical waveguide having a first and second waveguide provided with a width that allows propagation of light in a second-order mode or higher and a multimode optical interference waveguide provided with a wider width than the first and second waveguide and arranged at a position therebetween. The semiconductor light emitting element further includes a first optical loss layer facing the first waveguide in an active-layer crossing direction for causing a loss of light that is propagating in the first waveguide in the second-order mode or higher and a second optical loss layer facing the second waveguide in an active-layer crossing direction for causing a loss of light that is propagating in the second waveguide in the second-order mode or higher, the active-layer crossing direction being orthogonal to a surface of an active layer.

Abstract: An electric compressor has improved ability to connect an end of a stator winding with fastening terminals so that electrical connection can be established between the stator winding and the sealed terminal.The electric compressor includes lug terminal strips connected electrically to ends of lead wires from the stator winding each covered with an insulating tube, and fastening terminals connected through the lug terminal strips to the sealed terminal for supplying power to the electric elements.
