A method of optimizing the coupling to an optical fiber, including: generating a femtosecond laser pulse; directing a focus of the laser pulse to a longitudinal depth in the region beneath the endface of the optical fiber to generate microvoids; adjusting the intensity of the laser pulse at different depths, such that a refractive index profile is created in the region beneath the endface of the optical fiber.
