Abstract:
A micro-optical train manufacturing process includes a step of characterizing the position of optical components (114) on an optical bench (130), typically using a metrology system. These optical components (114) are then aligned with respect to each other in a passive alignment step (250) based on data from the metrology system and optical system design information. As a result, a subsequent active align process (260) can be avoided in some situations, or if a subsequent active alignment process (260) is performed, the time required for that active alignment process (260) can be reduced because of this initial metrology-based passive alignment step (250).
Abstract:
A process for tunable filter train alignment comprises detecting a spectral response of the filter train and aligning an optical fiber (10) that transmits an input optical signal to the filter train during operation. Further, the tunable filter (18) is moved relative to the filter train in response to a spectral response of the filter train. As a result, the alignment and spectral response of the tunable filter train are optimized. In the preferred embodiment, the alignment and SMSR optimization occur simultaneously with respect to each other.
