The present invention relates to a parallel optical interconnection module for
transmitting an optical signal over an optical fiber and receiving an optical signal
from the optical fiber. According to the present invention, a reflection surface
is formed at the end of the optical waveguide forming a core so that the path of
light can be exactly changed and is focused. A light source/photodetector is buried
within a trench using the silicon optical bench and an optical waveguide is manually
aligned on the surface of the silicon optical bench, so that alignment error between
the light source/photodetector and the optical waveguide can be minimized. A ferrule
into which the optical waveguide is inserted is fixed to an adaptor so that alignment
error between the optical waveguide and the light source/photodetector is minimized.
Therefore, the present invention can minimize the coupling loss in the process
during which the optical signal is transmitted to increase the optical output.
Further, the present invention allows easy optical interconnection by means of
a manual alignment and can increase the productivity.
