Abstract
Disclosed is an optical module which improves optical coupling efficiency either when configured to receive an optical signal from an optical fiber with a light receiving element or when configured to receive an optical signal from a light emitting element with an optical fiber. The optical module includes: a substrate () having in the surface thereof a first groove () and a second groove () formed, with this second groove () being configured to have a substantially V-shaped cross section formed deeper than the first groove and being formed in continuation from the first groove; and an internal waveguide () provided within the first groove () of the substrate (). The optical further modules a mirror portion () for changing an optical path, provided at the front end of the first groove (); an optical element () mounted on the surface of the substrate () so as to face the mirror portion (), and configured to emit an optical signal to a core () of the internal waveguide () via the mirror portion (). Moreover, the optical module further includes an optical fiber () having a fiber cladding () placed within the second groove () and a fiber core () optically connected to the core () of the internal waveguide ().
