Abstract
A thyristor may include a first optical waveguide segment in a semiconductor material, having first and second complementary longitudinal parts of opposite conductivity types configured to form a longitudinal bipolar junction therebetween. The thyristor may further include a second optical waveguide segment in a semiconductor material, adjacent the first waveguide segment and having first and second complementary longitudinal parts of opposite conductivity types configured to form a longitudinal bipolar junction therebetween. A transverse bipolar junction may be between the second longitudinal portions of the first and second waveguide segments. An electrical insulator may separate each of the first longitudinal portions from the waveguide segment adjacent thereto.
