Definitions
- the invention relates to a method of the type specified in the preamble of claim 1 and to devices of the type specified in the preamble of claim 2.
- Such a method, and devices therefor which presumably use comparatively complex fiber Bragg gratings as wavelength selectors as spectrometers , are known from an AT&T announcement 7.96.
- the wavelength-selective mixing and / or distribution of polychromatic light in the wavelength multiplex process is important in order to generate the wavelength mixture and to dissolve it again.
- the individual wavelengths with a kind are important in order to generate the wavelength mixture and to dissolve it again.
- Spectrometer selectively separated, the information recovered and distributed to different consumers after sorting the information.
- AT&T announcement 7.96 mentioned e.g. B. set up an optical network around Africa to supply the 51 states separately with 51 wavelengths.
- spectrometers for the decomposition of polychromatic light or light bundles of different specified wavelengths, as used for telecommunications in Multiplex wavelengths and used in optical measurement technology consist of prisms, gratings or fiber gratings and break down the incident spectrum into several spectrally limited light beams with a narrow wavelength.
- Fig. 1 shows the structure of a cascaded spectrometer, which is made up of photonic crystals and the spectrally selected light intensity with measures a photoresistor at the output of the crystal
- Fig. 2 the structure for a wavelength selective
- FIG. 3 shows the construction for a wavelength-selective multiplexer and adder, which selectively couples a certain wavelength into fibers and other networks through coupled fibers.
- the problem of wavelength-selective mixing and / or distribution is based on the simplest and most reliable selection possible when splitting the spectrum into a plurality of spectrally limited light beams of narrow wavelength range, which are also a decisive feature of a spectrometer.
- the further explanations are therefore based on the application for spectrometric measurements and lead to complete execution as a mixer and distributor.
- a spectrometer can also be constructed according to FIG. 1, with which the wavelengths present in the spectrum and the wavelengths to be examined can be selectively coupled out and analyzed. In addition to known light-sensitive ones, this can be used as a spectrometer for a measurement application
- Elements of conventional design such as phototransistors or charge coupled devices, or semiconductor diodes, advantageously a highly sensitive photoresistor made of nanocrystalline material, in accordance with DPA 196 21 175.1 or 197 20 926.2, can be used.
- the spectrometer By constructing the spectrometer from photonic crystals with a wavelength-specific design, the spectrometer can be built together with the light-detecting element integrated on a chip.
- Spectrometers of this type are therefore also inexpensively available for environmental monitoring tasks at emission sources. These can be mass-produced commercially using lithographic processes with high-resolution etching masks produced by deposition or corpuscular-beam-induced deposition in the projection device and with a high refractive index generated by silylation, in accordance with DPA 196 16 324.2. An “on-chip” spectrometer can be implemented in this way.
- wavelengths that are required for further processing can be selected here with specially designed, selectively acting filters with high resolution.
- the advantage of the method is the small size and the high selectivity in intensity and bandwidth.
- Such a spectrometer made of photon crystals for wavelength-selective beam splitting is integrated in a waveguide pattern in such a way that one wavelength is always filtered out of the entire spectrum for each crystal and the residual spectrum for the next crystal in the chain by highly efficient reflection for further splitting and transmission is fed.
- each spectrometer crystal there is a highly sensitive photoresistor in FIG. 1 for measuring the intensity, integrated in the arrangement or a conventional detector into which the light from the spectrometer crystal is coupled by waveguides or lenses.
- Such a spectrometer can, according to FIG. 2, be produced in the embodiment with photonic crystals from deposited dielectric rods with also deposited resistance by electron beam induced deposition. However, it can also produce in the version with photonic crystals from dielectric rods produced by dry etching with deposited resistance, which is produced by electron beam induced deposition.
- a spectrometer in the version with photonic crystals can be made with holes made in the dielectric by dry etching Matter and with integrated deposited resistance which was generated by electron beam induced deposition.
- the spectrometers described with photonic crystals can each be completed with optical fibers connected per spectral channel in accordance with FIG. 2 for the wavelength division of the spectrum of a multi-wavelength transmission path.
- This component can also be used for individual wavelengths as a mixer (add) and as a distributor (drop).
- a synthesizer is formed, according to FIG. 3, by the modification of such a spectrometer, which consists of photon crystals for wavelength-selective beam splitting, integrated in a waveguide pattern in the
- a synthesizer for assembling a spectrum from individual laser wavelengths the same elements of the spectrometer are operated.
- At the output of each spectrometer crystal there is a fiber laser or laser connection for coupling the light of the specific wavelength, with which the spectrum can be composed in the smallest space.
- Such a synthesizer (ADD) with connected optical fiber with per spectral channel, can be used for the wavelength composition of a spectrum with one or more additional wavelengths which are to be added to a multi-wavelength transmission link without influencing the spectrum of the link .
