Abstract:
1. A semiconductor laser, comprising: a semiconductor nanowire of a first conductivity type provided over a substrate; a light emitting layer provided around the semiconductor nanowire and insulated at an upper end and a lower end thereof; a cladding layer of a second conductivity type different from the first conductivity type, the cladding layer being provided at an outer periphery of the light emitting layer; a first electrode electrically coupled to an end portion of the semiconductor nanowire; a second electrode electrically coupled to an outer periphery of the cladding layer; a first reflection mirror provided at a one-end portion side of the semiconductor nanowire; and a second reflection mirror provided at the other end portion side of the semiconductor nanowire, wherein a refractive index n1 of a semiconductor material configuring the semiconductor nanowire, a refractive index n2 of a semiconductor material configuring the light emitting layer and a refractive index n3 of a semiconductor material configuring the cladding layer satisfy a relationship of n3<n1<n2, and any one of a condition that a product Δn·δ between a ratio Δn=(n
