Bipolar Junction Transistor Optical Modulator
Invention type: Technology
/
Case number: #22041
Semiconductor optical modulators are described that utilize bipolar junction transistor (BIT) structure within the optical modulator. The junctions within the BIT can be designed and biased to increase modulator efficiency and speed. An optical mode may be located in a selected region of the BIT structure to improve modulation efficiency. The BIT structure can be included in optical waveguides of interferometers and resonators to form optical modulators.
