Abstract

In this paper we present an integrated optical surface plasmon resonance sensor incorporating a gold electrode, to enable simultaneous electrochemical and optical measurements. The waveguides are fabricated from Pyrex, using photolithographic patterning and K ion-exchange and have been designed to incorporate a 'Y Junction' which allows simultaneous observation of a sensing and a reference output signal as shown in figure 1. Recent work has demonstrated that such a sensor provides high sensitivity to sub-monolayer changes at the gold electrode surface while allowing electrochemical control of the gold electrode surface.
