Abstract
A wedge filter for an optical sub-assembly for transceivers includes an incident face and an emission face. The incident face and the emission face contain an angle so as to change the refraction position of the incident light. Accordingly, the optical signal is incident upon the optical fiber of the optical sub-assembly for transceivers by a predetermined inclination angle so as to rectify the incident direction of the light emitted from the light-emitting element to be coaxial with the emission direction of the light of the optical fiber for achieving optical coupling efficiency.
