“…Polymers with high negative values of dn/dT are thus preferred for use in thermo-optic waveguide devices. 6,7 On the other hand, polymers exhibiting low negative values of dn/dT are preferred when fabricating athermal silica waveguide devices. For example, channel wavelength in dense wavelength division multiplexing devices is very sensitive to ambient temperature because of the temperature dependence of the optical path length of the silica core.…”

The thermo-optic coefficient (dn/dT) of inorganic-organic hybrid material films prepared by the sol-gel process of organoalkylsilanes is measured using a prism coupler equipped with a hot stage. The effect of the organic modifier on the variation of dn/dT in inorganic-organic hybrid material films has been investigated. The value of dn/dT becomes more negative with increasing molecular weight of the organic modifier or with an increase in the proportion of modifier in the sample. On the other hand, dn/dT increases with an increase in the degree of organic photopolymerization. From these results, it can be seen that the value of dn/dT in these films can be varied between −0.83 × 10 −4 /°C to −2.43 × 10 −4 /°C by changing the organic modifier concentration and type.

“…There are various types of optical switches using the well-known thermo-optic or electro-optic effect which have the configurations of planar lightwave circuit devices such as the directional coupler [1], the Mach-Zehnder interferometer [2], the X-junction [3], or the Y-branch [4]- [7]. Among them, polymer-based Y-branch digital optical switches (DOSs) are preferable due to the low power consumption resulting from the large thermo-optic coefficient of polymer materials and due to the low dependence on polarization and wavelength compared to interference-type switches [6]- [8].…”

A chromophore molecule-linked azo polymer as waveguide material (MCAP) of polymeric thermo-optic digital optical switch (DOS) was prepared with a chromophore molecule (ABFA), a polyether polyol and isophorone diisocyanate (IPDI). The chemical structures of ABFA monomer and azo polymer MCAP were characterized by FT-IR and UV-Visible spectroscopy. The thermal and mechanical properties of the MCAP¯lm were investigated. The refractive index and transmission loss of MCAP¯lm were measured at di®erent temperatures and different laser wavelengths by an attenuated total re°ection (ATR) technique and CCD digital imaging devices. A polymeric thermo-optic DOS based on the thermo-optic e®ect of the MCAP was designed and the performance of the switch was simulated by using the¯nite di®erence beam propagation method (FD-BPM). The experimental results showed that the power consumption of the polymeric thermo-optic switch could be only 0.64 mW, while the response time of the switch could be as short as 3.0 ms.
