| 摘要 |
An optical device including strained and non-strained regions along an optical medium. In one aspect of the present invention, strain-inducing material disposed proximate to the optical medium induces one or more perturbations of a refractive index along the optical medium to selectively reflect an optical beam directed through the optical medium having a first center wavelength back out a first end of an optical path as remaining wavelengths of light are propagated through a second end. In another embodiment, an optical device may include a strained region disposed in a non-strained region so that one or more perturbations of the refractive index compensates for birefringence of an optical beam directed through the optical medium.
