Abstract:
In general, in one aspect, the invention features methods that include guiding radiation at a first wavelength, λ1, through a core of a photonic crystal fiber and guiding radiation at a second wavelength, λ2, through the photonic crystal fiber, wherein |λ 1 - λ 2| > 100 nm.
Abstract:
A BST microwave device includes a substrate and an insulating layer that is formed on the substrate. A buffer layer is formed on the insulating layer. A BST layer is formed on the buffer layer with a selected orientation for high tunability and possesses a low loss in a wavelength of interest.
