Abstract
We demonstrate a technique for solving the general problem of light collimation from planar channel waveguides in both lateral and vertical directions. The reflowed polymer microlens technique enables direct on-chip integration and yields mass-fabrication feasibility. Beam propagation simulation on a 90-μm-diameter microlens results in a Gaussian beam with 46 μm diameter at a distance of 2.5 mm from the microlens. First test structures have been fabricated by reflowing photoresist cylinders with 81 μm height and 83 μm diameter. The resulting spherical lenses have the diameter of 89 μm. Optical investigation is ongoing.
