Abstract

Oppfinnelsen vedrører en PLC-(Planar Lightwave Circuit)-krets som innbefatter et to-trinns optisk filter til bruk i en bidireksjonal transceiver. Et første trinn omfatter et ikke-dispersivt optisk filter som slipper gjennom lys innenfor et bestemt bølgelengdespekter, f.eks. en signalkanal fra en laserkilde, som skal sendes til en inn/ut-bølgeleder, mens lys innenfor et annet bølgelengdespekter, f.eks. én eller flere detektorkanaler, vil bli rettet fra inn/ut-bølgelederen til et andre trinn. Det andre trinnet omfatter et reflekterende diffraksjonsgitter med en høyere oppløsning enn det første trinnet, som gir passbånd som er 2 til 5 ganger smalere enn det første trinnet.The invention relates to a PLC (Planar Lightwave Circuit) circuit which includes a two-stage optical filter for use in a bidirectional transceiver. A first step comprises a non-dispersive optical filter that transmits light within a particular wavelength range, e.g. a signal channel from a laser source to be transmitted to an in / out waveguide, while light within another wavelength range, e.g. one or more detector channels will be directed from the in / out waveguide to a second stage. The second stage comprises a reflective diffraction grating with a higher resolution than the first stage, which provides pass bands 2 to 5 times narrower than the first stage.
