Abstract
An optical modulator structure in a photonic integrated circuit includes an L-shaped P-N junction at an optical mode of the optical modulator structure (e.g., an area of the optical modulator structure in which light is generated). The L-shaped P-N junction provides increased area of overlap of the P-N junction at the optical mode relative to another type of junction, such as a horizontal junction or I-shaped junction. The increased area of overlap may enable the optical modulator structure to achieve a greater modulation efficiency.
