Abstract
An integrated optical device including: a composite substrate (1, 6) having a support substrate (1) and a laminated upper layer (6) formed on the support substrate, the upper layer having a preselected height and being capable of being selectively etched; a recess formed in the upper layer; a positioning hole (7, 8) formed in a surface portion of the support substrate exposed in the recess; a first optical component disposed on the surface of the upper layer; a second optical component guided by a portion of the recess and mounted on the surface of the support substrate; and a third optical component disposed in the positioning hole. Components having different height can be easily aligned on an optical axis.
