Abstract
The present invention discloses an optical fiber collimator suitable for coupling optical radiation from an optical fiber to an optical device, the optical fiber collimator comprising: a graded-index multi-mode fiber segment for receiving optical radiation transmitted by the input optical fiber; an optional mode field device, and a collimating lens for receiving optical radiation transmitted by the graded-index multi-mode fiber segment, the collimating lens for coupling the optical radiation into the optical device.
