Abstract
We report on a novel fused collimator design as part of a transmitter optical sub-assembly (TOSA) used for agile microwave photonic links. The fused collimator consists of a PM fiber that is laser fused to a C type lens. The fusion joint provides a low loss interface between the two components and eliminates the need for separate components in the optical path. The design simplifies the number of components with the optical assembly leading to several advantages over traditional designs. In this paper we use the fiber coupling efficiency as a design metric and discuss the optmechanical tolerances and its effect on the overall design parameters.
