The integration of Ge on Si for photonics applications has reached a high level of maturity:
Ge photodetectors are available on the Si platform in foundry processes, and Si/Ge …

Light polarization control is a target in photonics, and this paper provides a comprehensive
review of research from various groups on the silicon‐on‐insulator (SOI) platform. It draws …

Waveguide integrated optical modulators in the mid-infrared wavelength range are of
significant interest for molecular spectroscopy. This is because on-chip synchronous …

The design, modeling, micro-fabrication, and characterization of an ultra-broadband Ge-on-
Si waveguide polarization rotator are presented. The polarization rotator is based on the …

We demonstrate p-type SiGe quantum well infrared photodetectors (QWIPs) on a strained-
silicon-on-insulator (sSOI) substrate. The sSOI system allows strain-balancing between the …

It is challenging to simultaneously consider device dimension, polarization extinction ratio
(PER), insertion loss (IL), and operable bandwidth (BW) to design a polarization beam …

We present predictive simulations for a novel mid-infrared (MIR) polarization splitter and
rotator (PSR) design. It operates in the 3.1–3.6 m range, which is crucial for applications …

Abstract Chalcogenide compound Ge 2 Sb 2 Se 4 Te 1 (GSST), an emerging phase change
material, features drastic optical property contrast between the amorphous and crystalline …

A series of new mixed-substituted heteronuclear precursors with preformed Si–Ge bonds
has been synthesized via a two-step synthesis protocol. The molecular sources combine …

In this paper, a Si_3N_4− CaF_2 hybrid plasmonic waveguide (HPW) with an asymmetric
metal cladding is designed for the mid-infrared polarization rotator (PR). The mode …
