The present invention is directed to an assembly of an optical fiber and an optical fiber holder for holding the optical fiber, the optical fiber having an end surface formed at an end portion thereof, the end surface being configured to perform light coupling with a light emitting element or with a light receiving element. The optical fiber holder comprises; a throughhole which extends through the optical fiber holder and a recess that is positioned on a surface of the optical fiber holder and that is provided with an opening of the throughhole. The optical fiber is inserted through the throughhole and an adhesive is filled in a gap between an inner wall of the throughhole and an outer periphery of the optical fiber, the adhesive being used for adhering the optical fiber to the optical fiber holder. The end portion, on which is formed the end surface of the optical fiber, protrudes from the opening and terminates within the recess.

Assembly of optical fiber and optical fiber holder with end portion of optical fiber housed in recess

The invention relates to an optical module manufacturing method for bonding a can portion having an optical semiconductor element and a barrel portion of the optical module together, comprising the steps of: a bonding step for bonding a joint surface of the can portion and a joint surface of the barrel portion by thermoset adhesive, so as to form an interior room defined by the bonded can portion and barrel portion (S); a receiving step for receiving the bonded can portion and the barrel portion into a hermetical container (S); a curing step for heating interior of the hermetical container so as to solidify the thermoset adhesive dispensed on the joint surfaces (S); a cooling step for reducing a temperature inside the hermetical container after the thermoset adhesive is cured (S); and a step of taking the can portion and the barrel portion out from the hermetical container. The resin on the joint portion of the can portion and the barrel portion can be cured at a high temperature under condition that the can portion and the barrel portion are sealed together.
