Abstract
We reported the design and development of a dual-window SPR sensor, which is based on Ge-doped silica waveguide structure. By employing the WDM concept, a single waveguide can detect two or more kinds of samples in different ranges of wavelengths. The silica waveguides with low refractive index are good for lower SPR spectrum range in liquid. The two channels silica waveguide SPR sensors had been successfully fabricated and tested with two solutions, whose refractive indices are 1.361 and 1.418, respectively. The resultant spectrum has two resonant peaks at 626.41 nm and 751.8 nm, respectively.
