Abstract
[Object] To provide an optical coupling device that efficiently receives an optical signal from an optical fiber and has improved communication quality, and an optical communication system using the same. [Solving Means] An optical coupling device according to the present technology includes a light receiving and emitting device and an optical device. The light receiving and emitting device includes a light emitter that emits outgoing light, and a light receiver that receives incident light from outside. The light receiver has a light passing part through which the outgoing light passes. The light passing part is arranged on an optical axis of the incident light. The optical device causes incident light around the optical axis of the incident light to be refracted so as to be apart from the optical axis and to enter the light receiver.
