Paper Abstract
CMOS-compatible ring-based active devices have attracted significant attention for their ability to confine and
manipulate light on a compact SOI platform. Active modulation of a ring resonator is typically achieved by changing the
intensity response. As an alternative to intensity modulation, the phase modulation of the ring resonator can be converted
into intensity modulation of a Mach-Zehnder interferometer (MZI) by means of a ring-assisted Mach-Zehnder
interferometer (RAMZI) structure. We theoretically demonstrate an all-optical single resonance switching using a silicon
RAMZI by optically controlling the intracavity loss of the side-coupled silicon ring based on inverse Raman scattering
(IRS). The RAMZI structure improves the modulation robustness against fabrication deviations by relaxing the coupling
condition for the ring resonator, without compensating the modulation performance. In silicon, the IRS produces optical
loss with a bandwidth of 105 GHz at the anti-Stokes wavelength, which blueshifts 15.6 THz from the control light. For
our proposed RAMZI structure, the IRS induced loss is spectrally wider than the linewidth of the side-coupled ring, but
narrower than the free spectral range (FSR) of the ring, guaranteeing single resonance selectivity. When the control light
pulse of 200 ps switches from “off” (zero) to “on” (20pJ), the transmission of the anti-Stokes resonance transfers from
1.7% to 92.3%. The proposed structure provides the potential to multichannel all-optical routers on a CMOS compatible
platform.
