Abstract
An optical system includes optical devices that each have a top side and a bottom side between lateral sides. A first one of the devices has one or more first waveguides immobilized on a first base. The first device having a first via that defines an optical path that extends from the top side of the first device to the bottom side of the first device. A second one of the devices has a second waveguide immobilized on a second base. An optical fiber has a fiber facet immobilized relative to the first device and aligned with the first via. The first device is between the fiber facet and the second device. The first device, the second device and the optical fiber are arranged such that a light signal exchanged between the optical fiber and the second waveguide travels through the first via.
