We demonstrate post-fabrication trimming of individual silicon photonic slot-bridge nanobeam cavities using laser-assisted local surface oxidization. A permanent blue-shift of the fundamental resonance of up to 6 nm is observed, while the quality factor is enhanced by 54 % from 8100 to 12500.

We present our implementation of an on-chip FFT-based optical Convolution Neural Network. By exploiting the integration capabilities of Silicon Photonics, we can integrate high-speed optical FFT into a single Photonic Integrated Circuit (PIC), showing design, packaging, and initial results.

We experimentally demonstrate a high-resolution characterization setup for nanophotonic phased arrays. Waveguide modes are clearly observed in near-field radiation patterns of SiNx nano-antennas. This phased array has uniform emission throughout the antenna within 3dB bandwidth of 120 nm from 785 nm to 905 nm.

We characterize an integrated tunable optical phased array that directly generates multiplexed circularly polarized Orbital Angular Momentum (OAM) modes with highest mode counts demonstrated. We measured -12.7dB worst-case crosstalk for both modes examined and expect a uniformed performance among all supported modes.

850nm VCSEL arrays are cost-efficient light sources in dToF and iToF sensors for indoor 3D sensing applications. We designed highly efficient VCSELs at 850nm with a dual-metal architecture where two subsets of randomly interleaved emitters are electrically isolated and independently controlled.

Wave propagation through a chiral Fresnel zone plate (FZP) using diffractive analysis is adapted from the purely achiral FZP by incorporating the bimodal results for (RCP/LCP modes via Fresnel coefficients) corresponding to a magnetic chiral slab examined, leading to controllable on-axis foci and dual imaging.

Bidirectional incoherent optical frequency domain reflectometry exhibits confined spatial resolution through the Mach-Zehnder Modulator’s restricted bandwidth in backward direction. We propose hardware confined bandwidth exceedance by utilizing digital signal processing and therewith improve the spatial resolution by a factor of four.

Axisymmetric resonance modes within an electrowetting lens are investigated. We demonstrate that both electrical modulation and external axial vibration will lead to axisymmetric Bessel modes in an electrowetting lens device. The effect of optical system vibrations are mitigated through use of an electrowetting lens.

Given the ever-growing need for high-data rate, low-latency, secure, wireless communications driven by applications ranging from vehicle automation to ad-hoc battlefield command and control, free-space communication links (FSCLs) operating outside of the regulated and crowded rf-frequency bands are increasingly in demand. Recent research has verified that there are advantages to using MWIR and LWIR wavelengths for FSCLs through the atmosphere [1]. If the transmitter and receiver components can be developed to meet the FSCL requirements, this would enable lower latency than satellite links, greater security than rf, longer range than mm-wave, and greater availability than near-IR systems.
