“…The transmission loss, with a thickness of 4.5 m, was obtained at 25 C and the value was 0.230 dB/cm, comparatively smaller than in our previous works (0.659 and 0.565 dB/cm). 15,21 DOS have become, since their invention, a very attractive component for space switching in multi-wavelength optical communication systems applications. Therefore, the small optical transmission loss of the prepared MCAP has signi¯cance for developing a new DOS as waveguide material.…”

“…Various polymeric thermo-optic switches have been reported including digital optical switches (DOS), Mach-Zehnder interferometer switches, directional coupler switches, multimode interference/vertical coupler switches, and TO total-internal-re°ection switches. [14][15][16] Watanabe et al 17 reported a digital 1 Â 2 TO switch using waveguide silicone resin. The digital TO switches were characterized at 1.55 m. The power consumption and insertion loss of the transmission port were 130 mW and less than 2.5 dB, respectively.…”

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.
