Abstract
An optical device includes a common carrier, a first optical component and a second optical component that are supported by the common carrier, the first optical component being placed on the common carrier. This common carrier includes the following on a main surface thereof. The common carrier includes a first guide groove in which the second optical component is placed, a first beam passing groove extending from a vicinity of the first optical component along an optical axis so that a light beam emitted from the first optical component travels in the beam passing groove. The common carrier includes a second groove which is connected to the first guide groove and the first beam passing groove and extends in a first direction perpendicular to the optical axis, the second groove allowing the light beam to travel at a position lower than the main surface of the common carrier without being shaded.
