(a) Single MRR with one waveguide (inset: the cross-section of the device including the quasi-TE fundamental mode and dimensions of waveguide), (b) a tunable MRR-based optical switch with a PIN junction embedded in the ring, (c) the transmission spectra of the optical switch in block/pass mode (the status of the optical switch is from OFF to ON) for light with the working wavelength, black line is the spectra when the logic signal is ‘0’, blue line is the spectra when the logic signal is ‘1’, λ 0 marks the resonant wavelength without modulation, λ 1 marks the resonant wavelength after modulation, (d) the transmission spectra of the switch in pass/block mode (the status of the optical switch is from ON to OFF).
