Appeal No. 2006-2229
Application 10/347,069
Representative independent claim 12 is reproduced below:
12. A device to multiplex/de-multiplex light signals, the device
comprising:
optical components configured to multiplex light signals when
operated as a multiplexer and to de-multiplex light signals when operated as
a de-multiplexer, the light signals following external input and output optical
paths into and out of said device; and
a substrate configured with means for connecting to the external
optical paths, the substrate defining an optical path therein for the
multiplexed light signals and the de-multiplexed light signals, the substrate
comprising a material having a base refractive index and that includes at
least one region therein with a refractive index that differs from the base
refractive index, the substrate being configured for the light signals to pass
therethrough between the external input and output optical paths;
wherein at least one of the optical components comprises the region
with the different refractive index.
