These devices have been investigated in a seminal work conveyed in a former PhD work. It consists in the use of a nanoimprinted prismatic structure bonded on the surface of a PIC. Through evanescent coupling and reflections in the structure, guided waves can be transferred from the PIC toward an external optical system. With the use of electro-optic materials, this extractor may offer interesting applications as a switchable extractor. The candidate will delve into the theory of the device to improve its performance. He\/she will perform experiments on packaging, holography and PIC characterization. His\/her objective will be to manufacture a large panel of sample devices to be tested. One particular concern is to evaluate the behavior of the fabricated devices in a large spectral domain form visible to short Infra-Red wavelengths. The candidate will use FDTD simulation software to evaluate the propagation characteristics of the wave as it travels from a confined space to a free space. He\/she will define optimal prismatic structures to be replicated with nanoimprint. He\/she will implement the polymer structure on PIC samples through delicate transfer and bonding protocol in a clean room. He\/she will record micro-holographic optical elements with lasers to improve the angular potential of the final device. Large part of the PhD will concern the use of optical set-ups.<\/p>","protected":false},"featured_media":0,"template":"","categories":[185],"tags":[],"class_list":["post-12604","offre-emploi","type-offre-emploi","status-publish","hentry","category-photonique-imageurs-et-ecrans"],"acf":[],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/talentimpulse.cea.fr\/en\/wp-json\/wp\/v2\/offre-emploi\/12604","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/talentimpulse.cea.fr\/en\/wp-json\/wp\/v2\/offre-emploi"}],"about":[{"href":"https:\/\/talentimpulse.cea.fr\/en\/wp-json\/wp\/v2\/types\/offre-emploi"}],"wp:attachment":[{"href":"https:\/\/talentimpulse.cea.fr\/en\/wp-json\/wp\/v2\/media?parent=12604"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/talentimpulse.cea.fr\/en\/wp-json\/wp\/v2\/categories?post=12604"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/talentimpulse.cea.fr\/en\/wp-json\/wp\/v2\/tags?post=12604"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
