Recent breakthroughs in carrier depletion based silicon optical modulators
Graham T. Reed,Goran Z. Mashanovich,Frederic Y. Gardes,Milos Nedeljkovic,Youfang Hu,David J. Thomson,Ke Li,Peter R. Wilson,Sheng-Wen Chen,Shawn S. H. Hsu +9 more
TL;DR: The majority of the most successful optical modulators in silicon demonstrated in recent years operate via the plasma dispersion effect and are more specifically based upon free carrier depletion in a silicon rib waveguide as discussed by the authors.
Locally Erasable Couplers for Optical Device Testing in Silicon on Insulator
R. Topley,G. Martinez-Jimenez,Liam O'Faolain,Noel Healy,Sakellaris Mailis,David J. Thomson,Frederic Y. Gardes,Anna C. Peacock,David N. R. Payne,Goran Z. Mashanovich,Graham T. Reed +10 more
TL;DR: In this article, diffractive grating couplers, fabricated using lattice damage induced by ion implantation of germanium, are erased via localised laser annealing, which is shown to reduce the outcoupling efficiency by over 20dB after the device testing is completed.
Low-Loss Mid-Infrared SOI Slot Waveguides
TL;DR: In this paper, a silicon on insulator slot waveguides with a 1.4 ± 0.2 dB/cm propagation loss at 3.8 $\mu \text{m}$ wavelength is presented.
Suspended SOI waveguide with sub-wavelength grating cladding for mid-infrared
J. Soler Penades,Carlos Alonso-Ramos,Ali Z. Khokhar,Milos Nedeljkovic,L.A. Boodhoo,Alejandro Ortega-Moñux,Íñigo Molina-Fernández,Pavel Cheben,Goran Z. Mashanovich +8 more
TL;DR: A new type of mid-infrared silicon-on-insulator (SOI) waveguide that comprises a sub-wavelength lattice of holes acting as lateral cladding while at the same time allowing for the bottom oxide (BOX) removal by etching is presented.
Design Rules for Single-Mode and Polarization-Independent Silicon-on-Insulator Rib Waveguides Using Stress Engineering
TL;DR: In this article, simulations for both single-mode and polarization-independent behavior for small cross-sectional waveguides with variable rib width, etch depth, top oxide cover thickness, and side-wall angle are presented.
