Silicon photonics, with its CMOS compatibility and high integration density, has enabled a wide range of novel applications. Harnessing stimulated Brillouin scattering (SBS), an optomechanic interaction between optical and GHz acoustic waves, in sili

We report on the development of InP-based semiconductor amplifiers with a U-bend waveguide geometry having the input and output ports on one facet only. This waveguide geometry simplifies the chip alignment during the hybrid integration on silicon ph

A photonic integrated circuit (PIC) for the coherent combination of 32 input optical signals into a single output fiber is reported. The PIC was fabricated using a low-loss thick silicon-on-insulator (SOI) process and packaged with 32 input and 1 out

We propose a novel polarization rotator concept using two-dimensional (2D) anisotropic materials, such as molybdenum trioxide, on top of 3µm silicon waveguides. The in-plane anisotropic behaviour of 500 nm thick MoO3 flake is analysed and confirmed

In this paper, we have demonstrated the beam steering experiments with the help of our optical phased array devices. The lateral beam steering has been showed successfully with the wavelength through the tunable laser source. The number of output cha

The notion and the linguistic coinage of “errore popolare” is not as old as it is commonly believed, but comes from the history of medicine when in the late 16th Century, the Sorbonne’s professors labelled as “erreur populaire” the paracels

We show theoretically and experimentally how a flat-top second-order response can be achieved with a self-coupled single add-drop ring resonator based on two couplers with different splitting ratios. The resulting device is a 1x1 filter, reflecting l
