We report on enhancing the photon-extraction efficiency (PEE) of deterministic quantum dot (QD) microlenses via anti-reflection (AR) coating. The AR-coating deposited on top of the curved microlens surface is composed of a thin layer of Ta2O5, and is

An efficient approach to automatically configure and tune Vernier microring filters by utilizing hybrid optimization algorithms and robust characterization models is presented. Automatic tuning of a four-ring Vernier filter over the entire C-band is

Optical links are moving to higher and higher transmission speeds while shrinking to shorter and shorter ranges where optical links are envisaged even at the chip scale. The scaling in data speed and span of the optical links demands modulators to be

A grating-based approach to exciting higher order fiber modes in a few mode fibers is presented. By exploitation of higher order modes of silicon on insulator nanowaveguides and by the illumination of the grating from opposing ends, the LP01, LP11, a

We report on a novel Mach-Zehnder modulator monolithically integrated with drivers in a photonic BiCMOS technotogy. 112 Gb/s PAM4 is successfully transmitted over 60 km SSMF using bulk optical dispersion compensation and a feed-forward equalizer.

We report on the role of digital pre-emphasis in facilitating 64 Gbaud DP-64QAM coherent optical systems based on currently available commercial 32 Gbaud transceiver components. In particular, we vary the extent of digital pre-emphasis together with

The finite-element method is a preferred numerical method when electromagnetic fields at high accuracy are to be computed in nano-optics design. Here, we demonstrate a finite-element method using hp-adaptivity on tetrahedral meshes for computation of
