Abstract

A gradient-index lens couples light from a laser active region to a waveguide core. The gradient-index lens includes a plurality of bilayers, each of the bilayers having first and second material of respective first and second refractive indices. The bilayers conform to a planar base of the gradient-index lens and further conform to input and output sidewalls of the gradient-index lens. The input sidewall faces the laser active region and the output sidewall faces away from the laser active region. The input and output sidewalls are tilted at respective acute angles relative to the planar base.
