Silicon integrated multi-mode ring resonator

Mengyuan Ye et al.

Summary: The ring resonator is widely used as a filter, wavelength multiplexer and switch in silicon integrated circuits. Challenges arise in designing a ring resonator that can handle multimode signals simultaneously and maintain uniform transmission due to severe modal dispersion. This paper proposes and demonstrates a multi-mode ring resonator (MMRR) inspired by free space geometric optics, allowing arbitrary supporting modes and uniform transmittance, with experimental validation of a four-mode MMRR and cascaded MMRR structures.

Hybrid WDM-MDM transmitter with an integrated Si modulator array and a micro-resonator comb source

Can Li et al.

Summary: A multi-channel silicon photonic transmitter based on WDM and MDM was demonstrated, utilizing a silicon nitride Kerr frequency comb as the light source and silicon electro-optic modulators for optical modulation. By employing three wavelengths and two modes, the optical transmission capacity was increased to 150 Gb/s. The integration of WDM and MDM components with a compact optical comb source opens new avenues for high-capacity multi-dimensional optical transmission in the future.
