Abstract:
A single stage integrated wavelength multiplexing opto-electronic circuit for simultaneous bidirectional transmission and receiving operations, comprising:an optical coupler provided with waveguide connections at opposite sides thereof;first and second waveguides connected to the waveguide connections at a first side of the optical coupler;third and fourth waveguides connected to the waveguide connections at a second side opposite the first side of the optical coupler and interacting within the coupler with the first and second waveguides;a light signal source connected to at least one of the first and second waveguides and a light signal detector connected to at least one of the third and fourth waveguides, the light signal source and the light signal detector being tuned to different discrete wavelengths for transmitting and receiving;wavelength-selective filters provided at the waveguides connected to the light signal source and the light signal detector.
