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.
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.
