A fiber tail assembly (FTA) with a micro-lens formed in the fiber tip is used to couple the laser light out of the package and along the fiber. The FTA is soldered at two points where metallized bands are deposited on the fiber pigtail, one at a fiber mount near the diode where it can be soldered into alignment with the laser diode, and two at the snout which forms a feed through the housing and seal for the package. Typically, the FTA is metallized along its entire length within the package. In this invention the two-metallized bands are separated by a region that is unmetallized.

A microlens on the end of an optical fiber has reduced back reflections to a light source, such as a pump laser diode. In a particular embodiment, the microlens is lapped on two radii, at least one of which is offset from the center axis of the fiber, to form a point on the end of the fiber, thus reducing a surface for reflecting light back to the light source. In another embodiment, the microlens is formed with two different side surface angles to accommodate misalignment of the light source to the fiber mount. In another embodiment a Fresnel lens structure on the end of the fiber operates optically as an angled chisel lens.

Multi-mode diode emitters are stacked in a staircase formation to provide a spatially-mulitplexed output. Improved coupling efficiency is achieved by providing tilted collimated output beams that determine an effective step height of the stepped structure. Since the effective step height is dependent on the tilt angle, a variable number of emitters can be used inside packages having a same physical step height, while still attaining high coupling efficiency.

Introduced here are computer programs and computer-implemented techniques for generating and then managing a federated database that can be used to ascertain the risk in interacting with vendors. At a high level, the federated database allows knowledge regarding the reputation of vendors to be shared amongst different enterprises with which those vendors may interact. A threat detection platform may utilize the federated database when determining how to handle incoming emails from vendors.

A system comprises one or more processors. The system further comprises memory having computer readable instructions stored thereon that, when executed by the one or more processors, cause the system to: obtain a reference tree of nodes and linkages for a reference three dimensional volumetric representation of a branched anatomical formation in a reference state; based on the reference tree, generate a reference three dimensional geometric model; based on measurements from a sensor system, detect deformation of the branched anatomical formation; based on the detected deformation, obtain a deformed tree of nodes and linkages; and generate a three dimensional deformation field that represents the detected deformation of the branched anatomical formation.

Techniques for detecting instances of external fraud by monitoring digital activities that are performed with accounts associated with an enterprise are disclosed. In one example, a threat detection platform determines the likelihood that an incoming email is indicative of external fraud based on the context and content of the incoming email. To understand the risk posed by an incoming email, the threat detection platform may seek to determine not only whether the sender normally communicates with the recipient, but also whether the topic is one normally discussed by the sender and recipient. In this way, the threat detection platform can establish whether the incoming email deviates from past emails exchanged between the sender and recipient.
