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.

This work presents the design and characterization of multi-tip SiN inverse tapered edge couplers. Our measurements and simulations show that increasing the number of tips effectively improves the horizontal misalignment tolerance compared to conventional linear tapered edge couplers.

Penetrating vessels emanating from cortical surface vasculature and extending into the cortex are key perfused conduits to shuttle blood from superficial pial vessels to capillaries in parenchyma for nourishment of the neuronal tissues in the brain. Locating and counting the functional penetrating vessels is an interesting task to quantify the course of ischemia in blood occlusive events such as stroke, which has been automated using optical angiographic techniques. Here, we introduce a simpler method effective to identify and count the cortical penetrating vessels in automated manner.

A record-high zero-bias bandwidth of 78 GHz was achieved. The device includes a 100 nm uniform Ga0.81In0.19As0.65Sb0.35 absorber and 225 nm uniform InP collector layer.

Integrated photonics is growing in terms of technology maturity and circuit complexity. Although traditionally used in communications, democratizing the technology through open foundries has opened up the technology for many more applications. In this tutorial, I will discuss the main trends and opportunities.
