In this paper, two recent advances in silicon ring resonator biosensors are presented. First, we address the problem that due to the high index contrast, small deviations from perfect symmetry lift the degeneracy of the normal resonator mode. This severely deteriorates the quality of the output signal. To address this, we discuss an integrated interferometric approach to give access to the unsplit,...
We demonstrate an all-optical low-power 2R regenerator of 10-Gb/s non-return-to-zero data based on a 10- -diameter electrically pumped microdisk laser, which is heterogeneously integrated onto the silicon-on-insulator platform and processed in a CMOS pilot line. The scheme results in BER improvement 8and works for submilliwatt-level input signals. The laser operates in the continuous-wave...
