First silicon optical transmitter transmits data at 100 Gbps

Silicon photonics specialists at the Optoelectronics Research Center (ORC) demonstrated the first all-silicon optical transmitter that operates at 100 Gbps without digital signal processing. The new development is reported by Optica magazine.

The optical modulator nearly doubles the maximum data rate of modern devices, demonstrating the potential for low-power, low-cost all-silicon solutions. They avoid complicating manufacturing processes with new materials that are incompatible with CMOS.

CMOS (complementary metal-oxide-semiconductor; English CMOS, complementary metal-oxide-semiconductor) is a set of semiconductor technologies for constructing integrated circuits and the corresponding circuitry of microcircuits. The vast majority of modern digital microcircuits are precisely CMOS.

An optical modulator is an essential component in systems serving modern information and communication technologies. Moreover, not only in traditional data communication channels, but also in microwave photonics.

In contrast to previous work in this area, scientists have introduced a new modulator design concept in which photonics and electronics must be viewed as a single integrated system in order to solve complex technical problems in this area.
