摘要： An optical fluid flow sensor and methods are presented. An optical fiber bends in response to a fluid flow, and a light source coupled to the optical fiber transmits light to the optical fiber. Optical sensors surrounding a portion of the optical fiber receive a received light from the optical fiber, and a signal processor module estimates a fluid flow velocity of the fluid flow based on the received light.

摘要： A photonic crystal apparatus and method are provided. The photonic crystal apparatus includes an electromagnetic signal source configured to provide electromagnetic signals. The photonic crystal apparatus also includes a photonic crystal configured to receive the electromagnetic signals from the electromagnetic signal source and to direct the electromagnetic signals along a predefined path through the photonic crystal when the photonic crystal is undistorted. The photonic crystal apparatus may also include a driver configured to selectively cause a portion of the photonic crystal to alternate between a distorted state and an undistorted state. In instances in which the photonic crystal is in the distorted state, the photonic crystal is configured to redirect the electromagnetic signals in a different direction than the predefined path.
