Stimulated Emission Tomography (SET) is a technique which maps the Joint Spectral Amplitude (JSA) of photon pairs with extremely high signal to noise ratio and low integration times. While the modulus of the JSA is easy to access, the retrieval of the Joint Spectral Phase (JSP) is far more challenging and requires advanced interferometric techniques. Here we present and validate a scheme to measure the complex JSA by using a reconfigurable silicon chip. In particular, we map the rich structure of the JSP of a silicon microresonator.

A thermo-optic dynamics model and a novel form of induced transparency and corresponding slowlight based on thermo-optic dynamics is demonstrated in optically pumped silicon microcavities. The phenomenon provides group delay as high as 0.5 µs in a silicon photonic crystal cavity at room temperature.

A self-configuring mesh of silicon Mach-Zehnder Interferometers is employed to receive two spatially overlapped orthogonal beams modulated at 10 Gbit/s. These beams, sharing the same wavelength and state of polarization, are separated with more than 30 dB isolation, and sorted out with no signal degradation.

Concentrations down to 300 pM of the interleukin-6 biomarker, identified as an inflammatory marker for severe COVID-19 infection, have been detected in buffer using referenced microring resonators in the emerging Al2O3 integrated photonic platform. Antifouling was achieved by applying an Xantec HC1000M hydrogel.

We report on the characterization of a high channel count Optical Phased Array (OPA) at the wafer level. Using a modified prober, a 256 channel OPA has been successfully calibrated for +/-25° without requiring any packaging steps thus allowing for fast OPA testing.

Integrated optical antennas are relevant devices for the development of next-generation LIDAR systems. Here we experimentally demonstrate a new topology to implement long antennas in silicon-on-insulator platform. The designed 2-millimeter-long antenna presents a measured far-field beam divergence of 0.1° and a wavelength sensitivity of 0.13°/nm.

Frequency comb generation by means of electro-optic modulator is a straightforward and flexible technique for on-chip comb generation. A silicon depletion phase modulator is modeled numerically. By integrating this modulator in a racetrack resonator, a wideband comb can be generated with more than 100 lines.

We present a general method to design an op-tomechanical crystal cavity with multiple confined mechanical modes coupled to the same optical field. Notably, the mechanical modes are located in a full phononic bandgap. An experimental demonstration for a six transition unit cell cavity is demonstrated thus confirming the validity of the method.
