We employ the process of non-degenerate four-wave mixing Bragg scattering to demonstrate all-optical control in a silicon platform. In our configuration, a strong, non-information-carrying pump is mixed with a weak control pump and an input signal

Room temperature amplified spontaneous emission at mid-IR has been observed from optically pumped GeSn waveguides on Si. For higher pump power, emission spectrum indicates the direct band to indirect band emission intensity ratio increases and the pe

We experimentally demonstrate a transistor-like all-optical logic gate in a silicon waveguide via four-wave mixing Bragg scattering, and evaluate the eye diagrams using pseudorandom data.

Interference Lithography (IL) is a powerful and inexpensive tool for large area precision nanoscale patterning of periodic structures. In this work we extend IL's capability to create features in arbitrary shapes and locations through the use of bina

We demonstrate controlled wavelength conversion on a silicon chip based on four-wave mixing Bragg scattering (FWM-BS). A total conversion efficiency of 5% is achieved with strongly unbalanced pumps and a controlling peak power of 55 mW, while the eff

Pixelated wiregrids are of great interest in polarimetric imagers, but there are no straightforward methods available for combining the uniform exposures of laser interference with a masking system to achieve pixels at different rotational angles. In

We develop a new technique for integrating waveguide detectors in a silicon nitride photonic circuit. Fabrication relies on a novel method of selective oxidation as an alternative to chemical-mechanical-planarization with higher yield and tolerance.

We demonstrate low-noise low-power four-wave mixing Bragg scattering in a silicon-on-insulator platform as a possible controlled all-optical switch. Efficiency and quantum noise measurements are performed to verify the viability of the device.
