We are getting ready to perform the first tests on some polymer bandgap fibers. 

Ordered the (330micron and 125micron inner diameter) connectors for polishing the fiber about two weeks ago; however, we have not received them yet. We expect we would receive them this week or early next week). Last week we tried to use the 400micron-diameter connector to polish the 300micron-diameter Bragg fiber (we only have connector with diameter larger than 400micron). The polishing was not perfect due to the incompatibility between the connector and the fiber.

As an example, the typical facets of the Bragg fiber after polishing are shown in the figure attached here. Though some scratches and small speckles can be seen on the facets, they would no affect the performance of the Bragg fiber used as a bending sensor. Note that the polishing will be improved after we receive the new fiber connectors.
