Engineers have taken an important step toward the creation of a working optical transistor: precisely controlling the mixing of optical signals via tailored electric fields, and obtaining outputs ...

As proof of concept, the researchers demonstrated the operation of a transistor laser as a non-linear microwave mixing device and signal processor using a single emitter and a twin-contact base.

The mixing device accepts two electrical inputs and produces an optical signal that was measured at frequencies of up to 22.7 gigahertz. ... High-speed signal mixing, ...

Figure 1: Different configurations for signal regeneration using FWM. In summary, we have demonstrated all-optical regeneration of signals at low powers using FWM processes in a silicon nanowire ...

Designed with Point 2 Technology’s proven low-power, mixed-signal architecture in a leading CMOS process, the second-generation P1B120 SoC enables 800G active electrical cables (AECs) at 5W per ...
