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.
