Abstract
An optical modulecomprises an optical-receptacle housing, an optical-communication subassembly, and a holder. The flange portionhas a plurality of first portions, which extend along a reference plane perpendicular to a predetermined axis, Ax, and a plurality of second portions, each of which is positioned between the first portions. The outer periphery of the first portionsis positioned at the outside of a reference cylinder whose center is coincident with the predetermined axis Ax. The outer periphery of the second portionsis positioned at the inside of the reference cylinder. The optical-receptacle housingand the holderare temporarily fixed to each other at the second portionsof the flange portionthrough second bonding membersto. The optical-receptacle housingand the holderare further fixed with increased strength to each other at the first portionsof the flange portionthrough first bonding membersto. As a result, the deviation in optical alignment can be decreased to a small magnitude.
