Abstract: A sensor. In some embodiments, the sensor includes a first waveguide, a flexible support element, and a second waveguide. A first portion of the first waveguide may be supported by the flexible support element and separated by a first gap from a second portion of the first waveguide. The flexible support element may be capable of bending so as to cause an effective index of refraction of the first waveguide to change. The first waveguide may be coupled to the second waveguide through a second gap, the second gap being at an end of the first waveguide and an end of the second waveguide.
