Abstract :
The wavelength response of fibre to metal clad planar waveguide couplers has been investigated as a function of superstrate index. The TE resonance wavelengths remain fixed with superstrate index variation while the TM resonance position demonstrates good superstrate index sensitivity. Such a technique may be used for polarisation referencing and temperature compensation in refractometry
