ABSTRACT:
In present invention, a photonic integrated circuit includes a number of optical coupling ports that extend from the surface of the device through at least a dedicated fibre guiding layer or a planar structure for coupling the end of an optical fibre mounted within the optical coupling port to an underlying planar optical wave guide or other light emitting device so that, in use, light is coupled between the underlying optical wave guide or light emitting device and the optical fibre. The other and of the optical fibre may be coupled to an optical fibre holder or to another optical coupling port. An important advantage of the present invention is the flexibility it gives to a designer since it eliminates the need to for waveguides to be routed to the edge of the chip. It also solves the problem of aligning a large number of fibres onto a chip since the optical coupling ports allow fibres to be passively aligned.
