Silicon-based all-optical wavelength converter for on-chip optical interconnection

Abstract The study of silicon-based all-optical wavelength converters (SAOWCs) for on-chip optical interconnect applications holds potential research value and application horizons. The study proposes a SAOWC for on-chip optical interconnect technology. It also designs and optimizes an all-optical wavelength converter based on a quantum dot semiconductor optical amplifier and a Mach-Zönder interferometer in conjunction with photonic integrated circuit technology. The interlayer coupling efficiency is simulated by the finite-difference time-domain method, and the performance of the system is verified in conjunction with experiments. The experimental results showed that the coupling efficiency was as high as 98.44% at 1,550 nm wavelength. The bit error rate (BER) test results showed that the BER rose from 10 −17 to 10 −4 when the pulse width increased from 0.1 to 1.0 ps. Meanwhile, the temperature fluctuation and signal strength degradation tests further validated the stability of the device under different operating conditions. These results demonstrate that the converter has significant potential to enhance data transmission capability. The study provides a valuable reference for further improving and optimizing data transmission over all-optical networks, which is expected to promote scientific advancement and technological applications in this field.
