摘要
An apparatus includes an optical fiber configured to transport an optical signal. The optical fiber includes a core configured to receive and amplify the optical signal. The optical fiber also includes end features optically coupled to opposite ends of the core. The core has a lower bend loss than the end features. The optical fiber further includes a cladding surrounding the core and the end features. The optical fiber is configured to confine optical power of a fundamental mode in the core. The optical fiber is also configured to allow optical power of one or more higher-order modes to leak from the core into the end features.
