Abstract
We present here a study of the possible local heating effects in surface plasmon resonance sensors using low power lasers (∼mW/mm_2). By measuring the increase of electrical resistivity in an Au stripe while exciting SPR and performing numerical simulations we determine upper limits to the local heating that result of the order of ∼0.1K and ∼1K for laser power densities of 1.5 mW/mm2 and 15 mW/mm2 respectively.
