摘要：

Fluorinated polyimide waveguides with low polarization dependent loss (PDL) and thermooptic (TO) snitches made from them were demonstrated. The waveguides showed loss of less than 0.3 dB/cm at the wavelength of 1.3 mu m and 0.6 dB/cm at 1.55 mu m for both TE and TM polarizations. The PDL's were less than 0.1 dB/cm, Extinction ratios of Y-branching-type TO switches fabricated from these waveguides were larger than 20 dB when over 160 mW of electric power was applied at 1.3 mu m, and over 150 mW at 1.55 mu m, The switching speed was faster than 8 ms.
