Abstract
A photonics system comprising an optical circulator, comprising a plurality of ports; a first port arranged to receive a plurality of spatially separate optical signals each comprising a plurality of wavelengths; the optical circulator arranged to pass the plurality of optical signals to a second port so as to produce them as spatially separate signals; a plurality of optical wavelength filters arranged at the second port, in which each of the plurality of optical wavelength filters is arranged to align with a different one of the plurality of optical signals at the second port, each of the plurality of optical wavelength filters for selectively reflecting a selection of the plurality of wavelengths comprised in the respective optical signal and selectively passing others of the plurality of wavelengths.

A photonics system comprising an optical circulator, comprising a plurality of ports;
- a first port arranged to receive a plurality of spatially separate optical signals each comprising a plurality of wavelengths, the plurality of optical signals arranged to produce an array of spatially separate sources of light at the first port;
- the optical circulator arranged to pass the plurality of optical signals to a second port;
- focussing means for producing at the second port an image of each source of light, in which the images are spatially separate;
- a plurality of optical wavelength filters arranged at the second port, in which each of the plurality of optical wavelength filters is arranged to align with a different one of the plurality of optical signals at the second port, each of the plurality of optical wavelength filters for selectively reflecting a selection of the plurality of wavelengths comprised in the respective optical signal and selectively passing others of the plurality of wavelengths.
