Abstract
An optical device includes a laser or amplifier positioned on a base. The laser includes a ridge of a gain medium positioned on the base such that the base extends out from under the ridge. The ridge includes a top that connects lateral sides of the ridge. Electronics are configured to drive an electrical current through the ridge such that the electrical current passes through one or more of the lateral sides of the ridge.

An optical device, comprising:
- a laser positioned on a base, the laser including a ridge of a gain medium positioned on the base such that the base extends out from under the ridge,
- the ridge including a top and a bottom configured such that the bottom is between the top and the base,
- the top connects lateral sides of the ridge, and
- slab regions of the device are located on opposing sides of the ridge;
- and
- electronics are configured to drive an electrical current that flows from one of the slab regions to the slab region on the opposing side of the ridge with at least a portion of the electrical current passing through the ridge of the gain medium.
