A symmetry broken dielectric nanostructure that supports high-Q resonance is proposed to generate a wide range of pure visible colors. An antireflective coating layer is used to reduce reflection from a substrate. Almost 85.06% of sRGB and 64.77% of total color coverage are achieved from the structure.

In reservoir computing, semiconductor lasers with delayed feedback can efficiently solve difficult and time-consuming problems. The input data is optically injected into the laser. We show numerically that far better performance is observed using phase modulation of the injected field rather than intensity modulation.

We study the impact of the fiber Bragg grating feedback phase and the influence of feedback time-distribution, by employing gratings with different lengths, in the laser behavior. We report periodic stability enhancements linked with phase variations and stability oscillations when long, narrow-bandwidth gratings are considered.

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.

We report the first demonstration of a Raman laser in a sub-micron silicon-on-insulator waveguide operating above 2 μm. Lasing at 2.2 μm is obtained with a 0.7 μW output power. The laser efficiency is limited by the high signal loss.

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.

A FMCW signal in C-band is experimentally demonstrated using a tunable laser from an InP generic photonic integration platform. By applying a 100kHz-triangle voltage signal on an intra-cavity phase modulator, a frequency excursion of 2.7 GHz with high linearity correlation coefficient of 99.98% is achieved.

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.

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.
