(Z-cut/X-cut) waveguides are proved to be very interesting optoelectronic devices especially when
they are used like signal transducers in optical biosensing. The use of Z-cut and X-cut and the comparison between them
are frequently in optoelectronics but are rare in the field of biosensors. In this work, a comparison between two different
platforms for biomolecules detection will be done. The first platform uses an X-cut LiNbO
3
crystal and the second uses a Z-cut
one. After several tests, we have observed that the Z-cut platform induced many more losses and therefore a strong attenuation
of the signal.
