An optical waveguide bio-sensing device, comprising: a monochromatic light source, a beam splitter, a grating chip with a sub-wavelength grating structure and a sensor. Moreover, in order to enhance the sensitivity of the system using the optical waveguide bio-sensing device, a light concentrating element or a quarter waveplate (¼λ) is arranged in the optical path during detection.
