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 demonstrate the extraction of the dimensions of fabricated silicon nitride waveguides from the spectrum of a microring resonator. We show for the first time that this method is applicable with both the TE and TM polarizations.

Photonic processors have enabled applications in machine learning and neuromorphic computing. An information encoding/decoding scheme will be critical for scalable photonic computing. We experimentally demonstrate a "multi-level" encoding/decoding scheme and operation procedures.

Heterogeneously integrated III-V/Si MOSCAP de-interleavers with a channel spacing of 65 GHz are demonstrated in the O-band. Nth order AMZI and ring-assisted AMZI show flattop response with improved crosstalk performance via III-V/Si MOSCAP tuning.

We present a fabrication-robust silicon photonics platform compatible with standard 220 nm silicon thickness. Our generalized design methodology shows a 4× energy reduction over standard filter designs and was validated in a 300 mm foundry process, showing a promising avenue for reducing thermal tuning energy.

In this work we present the bricked subwavelength grating waveguide, a new topology capable of synthesizing metamaterials with lithographic control over anisotropy and dispersion. Experimental results in 2x2-90º couplers demonstrate its potential to design ultra-broadband and polarization management devices with practical feature sizes.
