14INTEGRATED OPTICAL CIRCUIT


DEFINITION

Classification: 385/14

INTEGRATED OPTICAL CIRCUIT:

(under the class definition) Subject matter wherein a combination of transparent, elongated structures or components are formed on a common substrate or chip of monolithic or hybrid construction.

(1) Note. Components in addition to the optical waveguide might include active optical elements (e.g., LED) or passive elements (e.g., lens).

(2) Note. An integrated optical circuit including a combination of an optical waveguide and a device of the Class 357 type is classified here provided the combination does not meet the requirement of a still larger system class.

129, for a planar optical waveguide structure which can be (but is not necessarily) the starting point for many integrated optical circuits.
