Abstract
A laser chip including a laser cavity that produces multiple laser outputs. A laser waveguide guides light through the laser cavity and has multiple output facets. Each of the laser outputs passes through one of the output facets. The laser waveguide guides the laser outputs such that the angle between the exit direction of different laser outputs is less than 180°. The exit direction for a laser output is the direction of propagation of light in the laser waveguide at one of the output facets.
Claims22
An optical system, comprising:
- a laser chip including a laser cavity that produces laser outputs,
- a laser waveguide guiding light through the laser cavity having multiple output facets, each of the laser outputs passing through one of the output facets,
- the laser waveguide guiding the laser outputs such that an angle between an exit direction for different laser outputs is less than 180°, the exit direction for a laser output being a direction of propagation of light in the laser waveguide at one of the output facets;
- and
- a planar optical device that receives the laser outputs from the laser chip without returning the laser outputs to the laser cavity.
(canceled)
An optical system, comprising:
- a laser chip including a laser cavity that produces laser outputs,
- the laser chip including lateral sides between a top side and a bottom side, and
- at least two of the laser outputs crossing the same lateral side of the laser chip;
- and
- a planar optical device that receives the laser outputs from the laser chip without returning the laser outputs to the laser cavity.
