AN INTEGRATED CIRCUIT OPTICAL INTERCONNECT

摘要

An integrated circuit optical interconnect for connecting a first circuit part arranged to output an optical signal and a second circuit part arranged to receive an optical signal. The integrated circuit optical interconnect comprises a body comprising a glass material. The glass material has embedded therein an optical waveguide arrangement having an input, located at a surface of the body, for coupling to the first circuit part, and an output, located at a surface of the body, for coupling to the second circuit part. The optical waveguide arrangement comprises at least two optical waveguide segments extending in different directions through the glass material and at least one reflecting part arranged between the two optical waveguide segments, for directing an optical signal from one of the optical waveguide segments to the other of the optical waveguide segments. The optical waveguide arrangement is arranged to optically couple the input and the output, whereby an optical signal can pass from the input to the output through the optical waveguide arrangement. There is also provided an integrated circuit module comprising the integrated circuit optical interconnect, and a telecommunications switch comprising the integrated circuit module. There is further provided a method for manufacturing an integrated circuit optical interconnect.
