| titleOfInvention | Apparatus And Method for Producing a Plurality of Coherent Light Outputs |
| abstract | Apparatus for the production of a plurality of coherent light outputs of individually selectable predetermined discrete wavelengths has a first wavelength selectable integrated laser assembly 1, and a second wavelength selectable integrated laser assembly 2. A third laser 3 is capable of generating an output comprising a fixed and predetermined wavelength. A means is used to pass the output of the first and second selectable integrated lasers and the output of the third laser through a medium 4 which allows the outputs from the lasers to interact in a non-linear manner. A filter 6 is used to remove the light at the original wavelengths so to produce an output 7 comprising essentially new generated predetermined discrete wavelengths. The medium 4 may comprise a four wave mixer. The number of wavelengths produced by the apparatus corresponds to the product of the number of wavelengths producible by the two individually selectable lasers. A method of producing a plurality of predetermined selectable discreet wavelengths of coherent light is also disclosed. The new generated predetermined discrete wavelengths may be modulated in response to data a stream 9. In place of the two selectable lasers, there may be three or more selectable lasers (12, 13, 17 see Figure 2), and there may be more than one fixed wavelength laser (33, 37 see Figure 3). Furthermore, the fixed and wavelength laser could be replaced with a multi-wavelength selectable laser. The filter may be a fixed wavelength filter such as a fibre Bragg grating or dielectric stack reflective or transmissive filter. |
