Abstract: The spectral linewidth variation of the light signal passing through the optical filter is employed to determine or evaluate the property of the analyte sample. By way of the optical filter, the light signal passing through the optical filter is affected by the analyte sample placed in the optical filter and the property of the analyte sample is determined by analyzing the resonating linewidth variation from the optical filter.

Abstract: An electro-optical modulator is provided. The electro-optical modulator has a substrate. A first insulator layer, an optical waveguide, a first doped semiconductor layer, a second insulator layer, a second doped semiconductor layer, and a third insulator layer are sequentially disposed over the substrate. The optical waveguide is adapted for transmitting a light wave. The optical waveguide includes a first semiconductor layer, a second semiconductor layer, and a third semiconductor layer. The first semiconductor layer is disposed on the first insulator layer. The first doped semiconductor layer is disposed on the first insulator layer, and positioned at two opposite sides of the optical waveguide for electrically connecting the optical waveguide. The second insulator layer is disposed on the substrate for covering the first doped semiconductor layer. The second doped semiconductor layer is disposed on the second insulator layer and electrically connected to the third semiconductor layer.

Abstract: An optical component is disclosed. The optical component includes a tap waveguide and a primary waveguide positioned on a base. The tap waveguide is configured to receive a portion of a light signal traveling along the primary waveguide. The portion of the light signal received by the tap waveguide is the tapped portion of the light signal. A direction changing region is configured to receive the tapped portion of the light signal from the tap waveguide and to direct the tapped portion of the light signal travels away from the base. A light sensor is configured to receive the tapped portion of the light signal from the direction changing region.
