Abstract
A tunable optoelectronic device comprising: a resonant grating filter exhibiting at least one filtering characteristic as electromagnetic radiation impinges thereupon; at least one dielectric material coupling said radiation onto said resonant grating filter and movably positioned with respect to said filter so as to adjust the at least one filtering characteristic of said filter; and, at least one driving circuit for selectively positioning said at least one dielectric material so as to tune said at least one filtering characteristic.
