As the sensors themselves do not need to contain expensive parts and the evaluation electronics can be shared by several cylinders (by using and combining
optical waveguides), manageable costs can be achieved.
Therefore, when UV light irradiates the sol-gel thin film through a photomask and the sol-gel film is dissolved in an organic solvent, the UV-irradiated parts remain intact on the substrate and form a patterned
optical waveguide with the resolution of 1 to 2 [micro]m.
An LiNb[O.sub.3]
optical waveguide of 26.5 mm was used for implementing a photonic filter, which introduced an OPD's of 2.2 mm, in agreement to eq.
Polymer
optical waveguides are not a new field of research.
Recently, our lab fabricated
optical waveguide channels to guide the on-chip light in a more reproducible manner to further improve the sensitivity down to a single-cell level or 1 picogram scale.
Numerous ways of all-optical gates without SOA using length of the fiber, waveguide, circulator, filters, acoustic-optic waves, and changing the refractive index of the
optical waveguide have been discussed in the first part.

Eigenvalue problems of
optical waveguide theory [5] are formulated on the base of the set of homogeneous Maxwell equations:
Polymer-based
optical waveguide is the basic light transmission medium for integrated optical device.
(5) DBR mirror: A "distributed Bragg reflector." A periodic structure formed on an
optical waveguide that reflects only the wavelengths of light corresponding to that period, transmitting all others.
