Abstract
A light distribution of light from a light-emitting device () has a higher luminous intensity in a first direction (D) compared to a reference direction (R), the first direction (D) being different from the reference direction (R). The reference direction (R) is a center direction of the light distribution, for example, a direction along the thickness direction of a substrate (), a direction along the width direction of each layer (for example, an EML ()) of a resonator (), or a normal direction of a second surface () of the substrate (). In addition, the light distribution has a higher luminous intensity in a second direction (D) compared to the reference direction (R), the second direction (D) being on an opposite side of the first direction (D) with respect to the reference direction (R).
