Abstract

We report optical bistability in Ge-based integrated ring resonators, namely Ge/Si and SiGe0.4/Si, in the mid-infrared (MIR) wavelength around 4 µm at low power levels of around ∼ 10 mW (on-chip). This shows the high potential of Ge-based microresonators for MIR nonlinear photonics.

Optical bistability in Mid-Infrared High Quality Factor Silicon-Germanium Resonators

We report Optical bistability in high-Q Silicon Germanium (SiGe) Ring Resonators in the Mid-Infrared (MIR) wavelength range between 3.5-4.6 μm. We numerically show that the high Q factor in combination with the observed nonlinearities is sufficient to generate soliton-based frequency comb.

Optical bistability in high-Q silicon-germanium ring resonators in the mid-infrared

We strongly improve the power coupling to high quality factor on-chip silicon germanium ring resonators by fabrication optimization and anti-reflection coatings. This allows us to demonstrate optical bistability on the silicon-germanium-on-silicon platform in the mid-infrared at wavelengths around 4.1µm.

Optical bistability on a silicon chip

Vilson R. Almeida, Michal F. Lipson

We demonstrate, for the first time to our knowledge, optical bistability on a highly integrated silicon device, using a 5-microm-radius ring resonator. The strong light-confinement nature of the resonator induces nonlinear optical response with low pump power. We show that the optical bistability allows all-optical functionalities, such as switching and memory with microsecond time response and a modulation depth of 10 dB, driven by pump power as low as 45 microW. Silicon optical bistability relies on a fast thermal nonlinear optical effect presenting a 500-kHz modulation bandwidth.

Thermo-optical bistability with Si nanocrystals in a whispering gallery mode resonator

Fernando Ramiro‐Manzano, N. Prtljaga, Lorenzo Pavesi +2 more

We report on the observation of optical bistability in an integrated planar microresonator with embedded silicon nanocrystals (Si-ncs). The phenomenon originates from the thermo-optical modulation of the silica-embedded Si-ncs refractive index, which in turn alters the spectral position of the resonator mode. The estimated thermo-optical coefficient of the Si nanocrystalline material, dn/dT≈2.92×10(-5)> K(-1), is an order of magnitude lower than that of bulk silicon. Both time-resolved pump-and-probe experiments and numerical simulations confirm that the silica host is responsible for the heat dissipation from the resonator. Moreover, a negligible Q-factor degradation at pump powers as high as 100 mW, along with the absence of a fast component in time-resolved measurements, confirm the minute contribution from excited carriers effects. These observations, combined with the already published large third-order nonlinearities of Si-ncs (an order of magnitude larger than in bulk Si), make this system an outstanding candidate for low-power on-chip nonlinear comb generation.

Optical Bistability in Chip-Scaled Ring Resonators

Giuseppe Brunetti, Caterina Ciminelli

Ring resonators are critical in optical systems for their compact size and high selectivity. By leveraging optical bistability-arising from nonlinear effects like the Kerr effect-they enable advanced functionalities, whose performance is strictly correlated to ring resonator ones. Here, a silicon nitride ring resonator, with a groundbreaking Q-factor > 150 million and extinction ratio> 5 dB by gaining from low optical losses and Kerr effect, is presented, unlocking new potentials for data storage, sensing and signal processing technologies.

Phase Controlled Bistability in Silicon Microring Resonators for Nonlinear Photonics

Riddhi Nandi, Arnab Goswami, Bijoy Krishna Das

Resonance shift and bistability in a silicon microring resonator operating at higher optical power levels pose serious difficulties, especially in nonlinear four wave mixing process. A solution of parking a laser wavelength around any of the resonances of a microring resonator and operating at any power levels is explored by integrating a microheater. We have shown with the existing theoretical model that the previous history of phase detuning in a silicon microring resonator determines the effective gain in stimulated four wave mixing process. The experimental results have been shown to be closely matching with the simulation results. For a microring resonator of radius 50 μm, an improved stimulated four wave mixing gain of ~ 11.6 dB has been observed while thermo-optically blue-shifting resonances in comparison to that of red-shifting resonances, for a launched pump power of 8.4 mW operating at a slightly off-resonant wavelength λp. The proposed technique can be used in designing actively controlled efficient photon sources in a large-scale integrated quantum photonic circuit operating at λ ~ 1550 nm.
