Abstract
A sensor includes at least one high refractive index layer; and at least one low refractive index layer coupled to the high refractive index layer.
Claims21
A sensor, comprising:
- at least one high refractive index layer;
- and
- at least one low refractive index layer coupled to the high refractive index layer.
A method of detecting at least one target species, the method comprising:
- binding the at least one target species to a waveguide layer;
- coupling light through the waveguide layer, the waveguide layer including at least one porous silicon layer having greater porosity than at least one second porous silicon layer;
- coupling light through the at least one second porous silicon layer;
- and
- identifying the at least one target species based on at least one of the coupling steps.
