Abstract:
A method of making a planar lightwave circuit (PLC) waveguide capable of being integrated with a surface-mounted component is presented. The method entails etching a silicon substrate to form a slanted wall, forming a nonreflective waveguide portion on the silicon substrate, and depositing a reflective layer on the slanted wall. Light travels through the nonreflective waveguide portion in substantially a first direction, and the light from the nonreflective waveguide portion strikes the reflective layer to be redirected in a second direction. The second direction may be the direction toward the surface-mounted component. A PLC waveguide device made with the above method is also presented.
