Abstract
The optic coupling device comprises optic emitting elements arranged in a coating material to emit a first light signal to an optic duct, and optic receiving elements separated from the emitting elements to receive a second light signal from the optic device. To improve the efficiency and simplify manufacturing, the optic receiving elements receive the second light signal through the coating material. An optic probe comprises the optic coupling device, an optic sensor, and an optic duct joining the coupling device and the sensor to transmit a first light signal to the sensor and to receive a second light signal to the coupling device. The communication device comprises two stations connected by an optic duct and comprising coupling devices.
