A fully polymer slot Young interferometer operating at
633 nm wavelength was fabricated by using nanoimprint
molding method. The phase response of the interference
pattern was measured with several concentrations of
glucose-water solutions, utilizing both TE and TM
polarization states. The sensor was experimentally found
to detect a bulk refractive index change of 6.4*10-6 RIU.
Temperature dependency of silicon slot waveguide has been
demonstrated to be reduced with composite slot waveguide
structure. The slot filled with thermally stable polymer
having negative thermo-optic coefficient showed nearly an
athermal operation of silicon slot waveguide.
Experimental results show that the slot waveguide
geometry covered with Ormocomp has thermo-optical
coefficient of 6 pm/K.
