摘要： An optical device includes a light-transmitting medium positioned on a base. The light-transmitting medium defines a waveguide. The optical device also includes a light sensor. The light sensor includes a light-absorbing medium positioned on the base. A portion of the waveguide ends at a facet such that a first portion of a light signal being guided by the wavegide passes through the facet and a second portion of the light signal bypasses the facet and remains in the light-transmitting medium. The light-absorbing medium is positioned on the light-transmitting medium such that the light-transmitting medium is between the light-absorbing medium and the base. Additionally, the light-absorbing medium is positioned on the light-transmitting medium such that the light-absorbing medium receives the first portion of the light signal that passes through the facet. Further, the light-absorbing medium is configured such that the second portion of the light signal is coupled into the light-absorbing medium from the light-transmitting medium.

摘要： The sensor includes an optical waveguide defined in a light-transmitting medium. The waveguide includes a sensing portion and an non-sensing portion. The light-transmitting medium included in the sensing portion has defects that provide the light-transmitting medium with a deep band gap level between a valence band of the light-transmitting medium and a conduction band of the light-transmitting medium. The deep band gap level is configured such that the waveguide guiding light signals through the light-transmitting medium in the sensing portion causes free carriers to be generated in the light-transmitting medium. A detector is configured to detect the free carriers in the sensing region of the waveguide.

摘要： The sensing system includes a plurality of modulators that are each configured to modulate a different light signal. The sensing system also includes optical pathways that transport the modulated light signals to one or more wavelength reflectors. Each wavelength reflector is configured to reflect a portion of the modulated light signals at a characteristic wavelength that is a function of an influence external to the wavelength reflector. The sensing system also includes a light sensor configured to receive the reflected light signals and to output a modulated electrical signal that is a function of the power of each of the reflected light signals. The sensing system can also include electronics configured to employ the modulated electrical signal so as to determine one or more results selected from a group consisting of: the characteristic wavelength of one or more of the wavelength reflectors and a level of the external influence on one or more of the wavelength reflectors. Examples of external influences include, but are not limited to, strain, stress, temperature, and properties of materials contacting the wavelength reflector such as index of refraction or pH.
