FIELD: physics.
SUBSTANCE: device is optical waveguides connected in pairs by Y-couplers into a single waveguide at the output of the circuit. Each subsequent coupler is connected to the output of the previous coupler and one of the inputs of the optical waveguides. Thus, based on the Y-couplers and optical waveguides, a device can be created for switching from a parallel code, transmitted over a set of lightguide filaments, to an analogue signal which, being converted to an electrical form later, can be interfaced with standard electrical cable lines.
EFFECT: enabling operation in single-mode conditions while interfacing analogue signals with digital signals.
