Patent ID: 7612881

Claim:
A method of alignment of an optical module, the optical module including a surface emitting laser mounted on a board for a photonic device with a luminous surface or an acceptance surface thereof formed in a direction reverse to the board and a lens member having a lens to be arranged at a position associated with the surface emitting laser, wherein the surface emitting laser and the lens are provided on the board in a prespecified positional relation, the method comprising the steps of; forming the lens member with an end face at a surface closer to a position at which the luminous surface or the acceptance surface of the surface emitting laser is provided than to a surface at which the lens included in the lens member is provided; providing an alignment mark representing the lens position on the end face of the lens member; and by making use of an image obtained by an optical device for visually recognizing a relation between the surface emitting laser and the alignment mark from a top surface of the lens member, performing positional control for the surface emitting laser and the lens such that the prespecified positional relation therefor is provided.
