Optical Wavelength Selection and Amplification by Silica Microcavities and Erbium Doped Fiber

摘要

In this paper we describe how circular silica micro disk resonators can be coupled to erbium doped fiber to create a desired emission spectrum. This approach could lead to very compact and inexpensive multiple wavelength lasers. We demonstrate here a selective erbium emission at a single wavelength using a silica microcavity.
