Abstract

in this work, we explore the sensing applications of Surface Plasmon Resonance (SPR) enhanced transmission of light through 1-D metal gratings on commonly available compact discs (CDs). We show that SPR on CDs (CD-SPR) can be used to build a simple and compact angular displacement measurement system with submicro- radian resolution. in addition we show that by controlling the azimuthal angle of the grating vector with respect to incident k-vector, it is also possible to measure angular displacement in two planes which is not possible with thin film SPR. The major advantage of this method is the compact form factor which will enable CD-SPR based angular measurement systems to be integrated into other experimental setups with the least burden.
