Biomimetic eXtremely-Birefringent Organic Optical Materials and devices

Objective

Man-made organic optics relies almost exclusively on amorphous polymers. These cheap, readily processable and highly versatile materials, however, offer a relatively low refractive index, dramatically limiting their ability to generate the high-index contrast necessary for producing scattering layers, photonic crystals and efficient dielectric reflectors. We here propose to establish a new class of novel organic crystalline optical materials and devices by drawing inspiration from the highly birefringent high-index organic molecular crystals nature has to offer, such as those found in dielectric reflectors, photonic crystals and photonic glasses that take part in structural coloration and vision. The crystal structure of these materials, is based on a planar arrangement of hydrogen bonded molecules, which are weakly bound by van-der Waals bonds and weaker hydrogen bonding.
The BoX-BOOM project aims to identify new cheap, functional and environmentally benign organic crystalline optical materials inspired by this structural motif, exhibited in biological systems, and to develop ways to grow them in a controllable manner as thin films using surface guided growth. The grown material will in turn be used in new types of optical elements and devices for a broad range of applications such as flat polarization optics, transparent dielectric metamaterials and birefringent volume holograms, all exploiting the high index and extreme birefringence of these materials. Work performed within the BoX-BOOM project will also shed light on the relationship between crystal structure and optical properties of this family of materials, setting the stage for identification of new high-index organic crystalline compounds and a range of applications taking advantage of this new thin-film optical technology.

Programme(s)

Multi-annual funding programmes that define the EU’s priorities for research and innovation.

Topic(s)

Calls for proposals are divided into topics. A topic defines a specific subject or area for which applicants can submit proposals. The description of a topic comprises its specific scope and the expected impact of the funded project.

Funding Scheme

Funding scheme (or “Type of Action”) inside a programme with common features. It specifies: the scope of what is funded; the reimbursement rate; specific evaluation criteria to qualify for funding; and the use of simplified forms of costs like lump sums.
