Beam transformations by active selfoc microlenses

摘要

In this paper light propagation in an active selfoc microlens with complex refractive index andgradient parameter are examined. The ray‐transfer matrix of an active material regarded as adiffraction‐free first order optical system is presented to describe the beam transformations in activeselfoc microlenses. Results concerning Gaussian beam transformations and on‐axis irradiancethrough the active selfoc microlens are discussed and commented.
