Abstract:
1. A laser system comprising: a first electrode to transmit first electrical carriers into an active region via a first waveguide region in response to first electrical stimulation; a second electrode to transmit second electrical carriers into the active region via a second waveguide region in response to second electrical stimulation, the first and second electrical carriers being combined in the active region to emit photons to generate an optical signal; and a third electrode responsive to third electrical stimulation to affect a concentration of third electrical carriers in a device layer located proximal to the second waveguide region to change a capacitance of an internal capacitance region associated with at least one of the first waveguide region, the second waveguide region, and the device layer, the third electrical stimulation being modulated to modulate the optical signal based on the change to the capacitance of the internal capacitance region.
