Optical channel monitor chip for monitoring an input signal with a plurality of signals of different wavelength ranges, with a chip input connector for receiving the input signal, with an optical coupler which forms out of the input signal a first intermediate signal and a second intermediate signal, wherein the first intermediate signal and the second intermediate signal respectively have the signals of all wavelength ranges of the signals of the input signal, with a first chip output connector where the first intermediate signal can be calipered, with a planar DWDM demultiplexer comprising a slab waveguide on the input side, a slab waveguide on the output side and an optical waveguide field connecting both these slab waveguides and a demultiplexer input connector on the input side waveguide by which the second intermediate signal is guided to the DWDM demultiplexer, and wherein by means of the DWDM demultiplexer the second intermediate signal can be split into the signals of the respective wavelength ranges, and which comprises DWDM demultiplexer output connectors on the output side slab waveguide which the signals of the respective wavelengths are guided to, and with at least a second chip output connector connected to a corresponding one of the DWDM demultiplexer output connectors (303), with an optical detector unit provided between the DWDM demultiplexer and the at least second chip output connector, wherein the optical coupler is integrated on the optical chip and the optical detector unit is directly connected to the DWDM demultiplexer output connectors at a chamfered edge of the optical channel monitor chip.
An optical channel monitor chip for monitoring an optical signal, said optical monitoring chip comprising:
- a first branching or coupling device for receiving an optical signal from an optical signal source and separating the optical signal into two signals of different amplitudes,
- a second branching or demultiplexing device for separating one of said two optical signals into its separate wavelength components,
- an optical detector device for receiving the signals from the branching or demultiplexing device and converting the received optical signals into electrical signals,
- optionally, sampling electronics having a plurality of receptors to receive the electrical from said optical detector device, and
- optionally, a device or element for receiving signals from said optional sampling electronic to thereby further process said signal according to an interpretation logic or a signal sampling logic to produce a logical output signal as an output;
- wherein said first branching or coupling device, said second branching or demultiplexing device and said optical detector device are integrated on the optical monitoring chip.
