We demonstrate the first quantum dot (QD) laser on a silicon substrate with efficient coupling
of light to a silicon waveguide under the QD gain region. Continuous wave operation up to …

We use the method of shortcuts to adiabaticity to design the variable couplings in a three-
waveguide directional coupler which may contain nonlinear elements, in order to …

In recent years, the concept of shortcuts to adiabaticity (STA), originally developed for
speeding up slow adiabatic state evolution in quantum systems, has found numerous …

We report a 2× 2 broadband and fabrication tolerant mode-evolution-based 3 dB coupler
based on silicon-on-insulator rib waveguides. The operating principle of the coupler is …

Co-packaged optics in next-generation datacenters require the assembly of multiple
components on the same multichip module (MCM) and interconnection with hundreds of …

A fully numerical method for designing efficient adiabatic mode evolution structure
(AMES)(referred to as NAMES) is introduced, which can be applied to adiabatic taper …

Broadband, low-loss, and fabrication-tolerant photonic passives are of paramount
importance in any photonic integrated circuit (PIC). Among others, the adiabatic couplers …

The fast quasi-adiabatic dynamics (FAQUAD) protocol has proven to be an effective
approach to provide shortcuts to adiabatic light evolution in optical waveguides, resulting in …

High-performance silicon-based edge couplers for interfacing with standard single-mode
fibers encounter significant challenges due to limitations imposed by the minimum …

Symmetric polarization rotator-splitter (PRS) is proposed and experimentally demonstrated
on InP for the first time. Instead of integrating a mode-selective splitter, we employ a …
