Optical system having dynamic waveguide alignment

摘要

The system includes a first optical device and a second optical device. The second optical device has a second facet. The first optical device has a waveguide on a base. The waveguide terminates at a waveguide facet. The waveguide facet is positioned so as to exchange light signals with the second facet. The first optical device also has one or more actuators that are each configured to move the waveguide facet relative to the second facet.

主权项

1. An optical system, comprising:
a semiconductor laser having a gain medium that terminates at a second facet; an optical device having a waveguide on a base,
the waveguide guiding light signals through a light-transmitting medium that terminates at a waveguide facet, the light-transmitting medium being different from the gain medium,the waveguide facet optically aligned with the second facet such that an optical pathway that light signals travel between the second facet and the waveguide facet does not pass through a second waveguide; andthe optical device having one or more actuators that are each configured to move the waveguide facet relative to the second facet such that a location where a line is incident on the second facet changes upon use of the actuator, the line being a line through the waveguide facet and parallel to the direction of propagation of light signals in the waveguide at a location that is both at the waveguide facet and on the waveguide side of the waveguide facet.
