Technologies have been developed based on silicon
chips that use a thin silicon dioxide film to form a common path
on chip interferometer [10-12]. The advantage of silicon chip
interferometric techniques is that the glass surface chemistries
developed for the well-established fluorescent microarrays may
be used. In this paper, we have presented the analysis of
interferometer consisting of a thin layer of gold embedded in a
silicon membrane. By using FullWAVE tool from R-Soft®. From
the results it is clear that interferometer consisting of a thin layer
of gold embedded in a silicon membrane is highly sensitive at
resonant wavelength range 1.615µm-1.625µm.

Test analyte is added to the gold (Au) layer. Observation
has been made out that the increment in the thickness of
gold (Au), decreases the magnetic intensity amplitude. So,
the incident light will have less power to simulate the
thickness of gold layer to produce the surface plasmon
resonance effect. Also observation has been made out that
difference in the test analyte refractive index of normal
cell and cancerous cell relatively changes in the output
power wherein the received output power for normal cell
is 0.0195 and for cancerous cell is 0.0165. It has been
observed that for the wavelength 1.615µm, there is distinct
shift in the output power. So it can be concluded that
sensitivity of sensor in the wavelength range 1.615µm-
1.625µm is very high.
