Title: Apparatus and method for compensating for misalignment in reflective packages

Abstract: An optical package includes a dual fiber termination having a first optical fiber end portion and a second optical fiber end portion. A collimating lens, spaced from the dual fiber termination, is configured for collimating and transmitting an optical signal emitted from the first optical fiber end portion and for converging a reflected optical signal onto the second optical fiber end portion. A mirror spaced from the collimating lens and having a reflective layer is configured and oriented for reflecting at least a portion of the emitted optical signal from the collimating lens back toward the collimating along a propagation path. A compensation lens is disposed between the collimating lens and the reflective layer of the mirror for correcting optical misalignment between the dual fiber termination and the collimating lens. The position of the compensation lens is movably adjusted in a direction transverse to the optical axis of the collimating lens and is configured for deflecting the emitted optical signal from the collimating lens to thereby modify the propagation path of the reflected optical signal such that the second optical fiber end portion receives the reflected optical signal without significant alignment-related optical loss.
