1. A method for transmitting a signal in an optical system, the method comprising:
- generating an optical signal;
manipulating the optical signal such that the optical signal defines a substantially annular intensity profile, where power of the optical signal varies in the intensity profile; and
launching the optical signal into an input face of an optical fiber such that a predetermined part of the intensity profile of the optical signal is located proximate an optical axis associated with the optical fiber.

Abstract
This disclosure concerns methods for transmitting a signal in an optical system. In one example, the method begins when an optical signal is generated. Then, the optical signal is manipulated such that the optical signal defines a substantially annular intensity profile, where power of the optical signal varies in the intensity profile. Finally, the optical signal is launched into an input face of an optical fiber such that a predetermined part of the intensity profile of the optical signal is located proximate an optical axis associated with the optical fiber.
