Integrated Photonics of Transistor Laser, Detector and Active Load for All Optical NOR Gate

The transistor laser is a promising candidate for high-speed integrated optoelectronics for its capability to operate under both base current modulation and collector tunneling modulation simultaneously, which fundamentally enables the monolithic integration of electrical and optical signal processing on the device level. This work demonstrates one of such applications by building an optical-to-optical NOR gate with the transistor laser in an integrated form.
