Abstract
A light emitting and receiving device consists of a light propagating member provided with a light emitting means for converting first electrical signals into first optical signals, and a light receiving means for receiving and converting second optical signals into second electrical signals. The light receiving means is disposed coaxially with an optical fiber. The light propagating member is situated between the optical fiber and the light receiving means. The light emitting means emits the first optical signals into the optical fiber, and the light propagating member receives from the optical fiber and propagates therethrough the second optical signals to the light receiving means. Loss of optical power is suppressed, and a downsized light emitting and receiving device is attained.
