Abstract:
A method of providing a point to point connection between two electrical circuit boards comprising:(i) providing a pair of optical transceivers, each formed on a silicon-on-insulator chip and each being in electrical contact with one of the said circuit boards, each optical transceiver comprising: (a) a branched rib waveguide comprising a common stem and first and second branches extending from the common stem; (b) fibre connection means for receiving an optical fibre, and being in communication with the stem of the branched rib waveguide; (c) a light source for providing optical signals, the light source being in communication with the first branch of the branched rib waveguide; and (d) a light receiver in communication with the second branch of the branched rib waveguide; and (ii) providing a single optical fibre linking the stem of the branched rib waveguide of the first transceiver to the stem of the branched rib waveguide of the second transceiver.
