1. A method of using a waveguide grating comprising:
- providing a waveguide grating device, comprising;
at least one waveguide having an end, the end having an endface; and
a waveguide grating fabricated on the endface of the at least one waveguide, the waveguide grating having at least one waveguide layer and at least one grating layer;
contacting the waveguide grating with a medium;
propagating a signal having at least one signal attribute through the at least one waveguide such that the signal contacts the waveguide grating, the waveguide grating being configured such that the at least one signal attribute is consequently modified;
determining at least one parameter of the medium using the modified signal attribute; and
outputting the at least one parameter.

Abstract
Methods of detecting one or more parameters of a medium are disclosed. The methods include providing a waveguide grating device, contacting the waveguide grating with a medium, propagating a signal having at least one signal attribute through the waveguide, and comparing the modified signal attribute to a known signal attribute to detect a parameter of the medium.
