Abstract

An alignment device includes an alignment member with one or more waveguide-alignment grooves, resonator alignment grooves, and/or an alignment groove for a second optical element such as a modulator. The various alignment grooves reliably establish and stably maintain evanescent optical coupling between the optical elements positioned therein. A method for assembling a resonant optical power control device may include: fabricating an alignment member with the alignment grooves; positioning and securing the optical elements in corresponding alignment grooves for optical coupling therebetween. Alignment grooves in the substrate and/or in one or more of the optical elements are fabricated at proper depths and positions and preferably with mating grooves and/or flanges to enable optical coupling without extensive active alignment procedures.
