Bragg grating based planar integrated optical circuit technology is applied to biosensors. Varieties of detection mechanisms such as antigen-antibody are investigated and an appropriate structures of Bragg grating optical sensors circuit is demonstrated. Trenches are fabricated onto a planar waveguide substrate and polymer core material with high refractive index is deposited in these trenches.Bragg gratings are formed onto this polymer core and series of Bragg gratings with different periods are fabricated along these waveguides. These waveguides are repeated in serial such repetition makes 2-D array of bio sensors which might be vey effective in sensing of disease. We will introduce and demonstrate the Bragg grating based silica waveguide sensors in this paper and some theoretical designs will be considered.
