Abstract: An optical device includes a chip, a set of waveguides on the chip and configured to carry first optical signals modulated with data during a data transmission stage, and an alignment waveguide on the chip. The alignment waveguide is configured to receive a second optical signal during an alignment stage that aligns the set of waveguides with a collimator including a set of lenses. The alignment waveguide is configured to output the second optical signal from the chip. The second optical signal output from the chip is indicative of a quality of alignment between the set of waveguides and the collimator.
