Abstract
This invention concerns an optoelectronic device, characterized in that it comprises, integrated by deposition in a single epitaxy on a semi-insulating substrate: at least one mode adapter (T), at least one optical amplifier (OA), at least one filter (MUX) capable of separating different wavelengths of the signal, at least one photodetector (D) and at least one guide (G) ensuring the link between the above-mentioned elements.
Claims38
An optoelectronic device for separating optical signals of different wavelengths arriving from a similar input comprising:
- at least one input channel comprising a first wide-mode guide which leads to an optical amplifier,
- a first mode adapter provided upstream from said optical amplifier on said first wide-mode guide, a second mode adapter provided downstream from said optical amplifier and which leads to a second wide-mode guide, and
- at least one wavelength separator filter capable of separating different wavelengths of a signal, said filter being connected to an output of said second wide-mode guide and comprising two diopters and a series of guides placed facing respective mirrors between the diopters to define optical paths of different lengths, and at least one output channel comprising a guide leading by way of a third mode adapter from the filter to at least one photodetector,
- wherein said input channel, said first mode adapter, and said wavelength separator are integrated by deposition in a single epitaxy on a semi-insulating substrate.
An optoelectronic device for separating optical signals of different wavelengths arriving from the same input, comprising:
- at least one input channel including a first optical guide,
- at least one wavelength separator filter capable of separating different wavelengths of a signal, said filter being connected to an output of said first optical guide and including two diopters and a series of guides placed facing respective mirrors between the diopters to define optical paths of different lengths, and
- at least one output channel including a second optical guide leading via a mode adapter from an output of said filter to an optical amplifier and a photodetector connected to the output of said optical amplifier,
- wherein said input channel, said wavelength separator, and said output channel are integrated by deposition in a single epitaxy on a semi-insulating substrate.
A filter integrated by deposition in a single epitaxy on a semi-insulating substrate, for separating different wavelengths of a signal, comprising two diopters and a series of guides placed facing respective mirrors between the diopters to define optical paths of different lengths.
