Abstract
A method of providing a point to point connection between two electrical circuit boards ( ) in which a plurality of pairs of optical transceivers are provided, one transceiver of each pair being formed on a first silicon-on-insulator chip ( ) in electrical contact with a first electrical circuit board ( ), and the other transceiver of each pair being formed on a second silicon-on-insulator chip ( ) in electrical contact with a second electrical circuit board ( ). Each optical transceiver comprises a branched rib waveguide comprising a common stem ( ) and first and second branches ( ) extending from the common stem ( ); a fiber connector ( ) for receiving an optical fiber ( ) in communication with the stem ( ) of the branched rib waveguide; a light source ( ) in communication with the first branch ( ) of the branched rib waveguide; and a light receiver ( ) in communication with the second branch ( ) of the branched rib waveguide. Each pair of transceivers is linked by an optical fiber ( ) connected to the stem ( ) of the branched rib waveguide of the first transceiver and to the stem ( ) of the branched rib waveguide of the second transceiver.
