Abstract
An optical module comprises: a sub-mount, having four photodiodesand two guide groovesdisposed on an optical element mounting surface; a fiber fixing member, having four V-grooves, four concave mirrors, and two guide railsdisposed on an optical fiber fixing surface; and four optical fibers, fixed to the fiber fixing member. With this optical module, the sub-mountand fiber fixing memberare aligned and fixed by the fitting together of the guide groovesand guide rails. A passive alignment type optical module that enables mass production and cost reduction is thus realized.
