Abstract
A multilayer optical device includes an arrangement, on a substrate, of a first layer, a second layer, and a space therebetween. The second layer is a thin-film. The arrangement of the first and second layers and the space therebetween produces transmitted, reflected, or dispersed spectrally modified electromagnetic energy from electromagnetic energy incident upon the arrangement. An optical function of the device is dependent at least in part on interference effects. An optical detector system includes a similar multilayer optical device. The space within the device is in fluid communication with structures for receiving a fluid such that the device operates in a first or second mode depending on absence or presence of the fluid within the space. The system includes a detector for receiving the modified electromagnetic energy, and a controller in fluid communication with the space that establishes the absence or presence of the fluid in the space.
