  We investigate the effect of a waveguide on an emitter spontaneous emission
in its vicinity. The impact of various possible orientations of an emitter with
respect to the waveguide surface is studied through simulations and compared
with experimental demonstration. Quantum emitters are dip coated on waveguides
and Purcell enhancement and a decrease in the lifetime of the emitter are
observed. This study serves as a proof of concept for the Purcell effect
offered by waveguides and helps ineffectively estimate the efficiency of
waveguide-based evanescent sensors and quantum photonic applications
