Abstract

We present progress in the development of the monolithic achromatic nulling interference coronagraph (MANIC), a nulling optic designed to enable direct imaging of nearby Jupiter-like exoplanets. The experimental testbed for measuring the optical path difference (OPD) between the two arms of the nuller and characterizing the nuller's performance is described. The OPD measurement will be used to determine the relative thicknesses of compensator plates needed to complete MANIC's fabrication. Demonstrating the performance of the monolith will include sub-aperture nulling of laser and white-light sources using a single PZT-controlled delay line on one half of a bisected input beam.
