• The structure of a surfactant molecule consists of two groups, a hydrophilic and a hydrophobic group. The possibility of detection of the critical micelle concentration (CMC) was examined using optical fibers, plastic cladding silica fiber (PCS) and plastic optical fiber (POF), with hydrophilic and hydrophobic core properties, respectively. The cladding was removed at the sensing region and the core was exposed to the sample solution. The output from both the PCS and POF increased drastically at the CMC of 3×10^<-3> mol/l. This was due to the rapid increase in the reflectance at the interface between the core and the sample solution as the surfactant molecules in the saturated solution began to adsorb onto the sensing region of the core surface.
