Comptez entre 2 000 et 4 000 pour une fenêtre de taille moyenne. Le prix pour l’agrandissement d’une fenêtre dépend de la complexité des travaux et des matériaux utilisés pour le nouveau vitrage. These results represents a first step towards a highly sensitive bio-sensor, including a diamond surface functionalization for specific target recognition. Généralement, il propose un forfait pour l’ensemble du chantier. A GMR with a c/100 group velocity at a wavelength of 800 nm was measured and its sensitivity is estimated to be in the order of 500 degrees/ refractive index unit (°/RIU), a value that is one order of magnitude higher than the typical values encountered for sensors based on 2D PhC. The technological processes required for the realization of PhC on polycrustalline diamond were developed or optimized, such as surface planarization by inductively coupled plasma (ICP) dry etching, diamond film transfer onto new substrate by wafer bonding process, diamond films thinning and surface patterning with PhC using Electronic Beam Lithography (EBL) and ICP methods.The samples realized in clean-room facilities were optically measured and the theoretical assumptions were validated. Drama Margot Santorini is an aristocratic woman in 1936 in Greece, who amuses herself pursuing a shallow loveless affair with a nobleman, but unexpectedly falls in love with a political activist. The proposed design is based on measuring the shift of the angular reflectivity of a low group velocity guided mode resonance (GMR) PhC when probed with a single frequency light.Polycrystalline diamond films were grown on two different substrates, with thicknesses ranging from a few hundreds of nanometers to several micrometers. Numerical methods gave the necessary information to determine the optimal geometrical parameters of the PhC. It was analytically proven that modes with low group velocity are more sensitive to these variations. In this context, this PhD thesis propose a new design of optical bio-sensor based on diamond two-dimensional photonic crystals, working at the wavelength near 800 nm.An original geometry of circular air holes arranged in squared lattice was chosen in order to maximize the sensitivity of such photonic structures to refractive index changes on their surface. Ce que vous devez absolument remarquer c’est les indices que vos fenêtres doivent être. Vos fenêtres peuvent très bien atteindre une durée de vie de 20 ans et souvent plus. Moreover, the use of diamond as material make the proposed device more attractive due to its optical properties, high chemical stability and efficiency of surface functionalization. Selon plusieurs experts, saviez-vous que la durée de vie d’une fenêtre est estimée à 15 ans Par contre, il ne faut pas prendre ceci comme vérité absolue. Among all the methods proposed, photonic crystals (PhC) structures offers a good alternative due to their sensitivity. Over the last years, the research on the label-free biosensor topic has experienced a very rapid growth because of the need to develop high-performing methods to detect and measure low concentrations of specific molecules in various fields.
