INTEGRATED WAVEGUIDE STRUCTURE FOR FLUORESCENCE ANALYSIS

摘要

An integrated waveguide structure (100) comprises a substrate (104) and a waveguide layer on top thereof. The waveguide layer comprises an excitation waveguide (101) for transmitting excitation radiation to activate a fluorescent particle, an emission waveguide (102) configured for transmitting radiation emitted by the fluorescent particle and a particle radiation coupler (106) being a resonator element arranged for coupling radiation emitted by the fluorescent particle into the emission waveguide (102). The structure also comprises at least one sensing site (103) configured with respect to the at least one excitation waveguide (101) and emission waveguide (102) such that a fluorescent particle at the sensing site is activated by the excitation radiation transmitted via the at least one excitation waveguide (101) and radiation emitted by the fluorescent particle is coupled into the emission waveguide (102) by the particle radiation coupler (106).
