A SiGe Slot Approach for Enhancing Strain Induced Pockels Effect in the Mid-IR Range

Olivares-Sánchez-Mellado, Irene; Sanchis Kilders, Pablo (Institute of Electrical and Electronics Engineers, 2021-08-15)

[EN] Strained silicon was proposed more than a decade ago promising to revolutionize the silicon photonics field by allowing efficient modulation in this platform. Despite all the efforts, still rather low chi(2) values ...
Development of Photonic Devices Based on the Strained Silicon Technology

Olivares Sánchez-Mellado, Irene (Universitat Politècnica de València, 2021-05-31)

[ES] En la última década, la plataforma de silicio ha emergido como la plataforma por excelencia para desarrollar circuitos fotónicos integrados debido a su versatilidad, la posibilidad de miniaturización y de una ...
Enhanced Pockels effect in strained silicon by means of a SiGe/Si/SiGe slot structure

Olivares-Sánchez-Mellado, Irene; Sanchis Kilders, Pablo (IEEE, 2020-10-01)

[EN] A slot waveguide structure made of a SiGe/Si/SiGe heterojunction is proposed to enhance Pockels effect in strained silicon. The strain is applied via lattice mismatch between layers, while the slot configuration ...
Enhancing Pockels effect in strained silicon waveguides

Olivares-Sánchez-Mellado, Irene; Parra Gómez, Jorge; Brimont, Antoine Christian Jacques; Sanchis Kilders, Pablo (The Optical Society, 2019-09-16)

[EN] The magnitude and origin of the electro-optic measurements in strained silicon devices has been lately the object of a great controversy. Furthermore, recent works underline the importance of the masking effect of ...
Experimental demonstration of a tunable transverse electric pass polarizer based on hybrid VO2/silicon technology

Sánchez Diana, Luis David; Olivares-Sánchez-Mellado, Irene; Parra Gómez, Jorge; Menghini, Mariela; Homm, Pia; Locquet, Jean-Pierre; Sanchis Kilders, Pablo (The Optical Society, 2018-08-01)

[EN] A tunable transverse electric (TE) pass polarizer is demonstrated based on hybrid vanadium dioxide/silicon (VO2/Si) technology. The 20-mu m-long TE pass polarizer exploits the phase transition of the active VO2 material ...
Non-volatile epsilon-near-zero readout memory

Parra Gómez, Jorge; Olivares-Sánchez-Mellado, Irene; Brimont, Antoine Christian Jacques; Sanchis Kilders, Pablo (The Optical Society, 2019-08-15)

[EN] The lack of memory effect of silicon makes it unfeasible to store electronic data in photonics. Here we propose a nonvolatile readout photonic memory, which is electronically written/erased and optically read. The ...
Non-Volatile Photonic Memory Based on a SAHAS Configuration

Olivares-Sánchez-Mellado, Irene; Parra Gómez, Jorge; Sanchis Kilders, Pablo (Institute of Electrical and Electronics Engineers, 2021-04)

[EN] The non-volatile memory is a crucial functionality for a wide range of applications in photonic integrated circuits, however, it still poses a challenge in silicon photonic technology. This problem has been overcome ...
On the influence of interface charging dynamics and stressing conditions in strained silicon devices

Olivares-Sánchez-Mellado, Irene; Ivanova-Angelova, Todora; Sanchis Kilders, Pablo (Nature Publishing Group, 2017)

[EN] The performance of strained silicon devices based on the deposition of a top silicon nitride layer with high stress have been thoroughly analyzed by means of simulations and experimental results. Results clearly ...
Optical switching in hybrid VO2/Si waveguides thermally triggered by lateral microheaters

Olivares-Sánchez-Mellado, Irene; Sánchez Diana, Luis David; Parra Gómez, Jorge; Larrea-Luzuriaga, Roberto Alejandro; Griol Barres, Amadeu; Menghini, Mariela; Homm, Pia; Jang, Lee-Woon; van Bilzen, Bart; Seo, Jin Won; Locquet, Jean-Pierre; Sanchis Kilders, Pablo (The Optical Society, 2018-05-14)

[EN] The performance of optical devices relying in vanadium dioxide (VO2) technology compatible with the silicon platform depends on the polarization of light and VO2 properties. In this work, optical switching in hybrid ...
Toward Nonvolatile Switching in Silicon Photonic Devices

Parra Gómez, Jorge; Olivares-Sánchez-Mellado, Irene; Brimont, Antoine Christian Jacques; Sanchis Kilders, Pablo (John Wiley & Sons, 2021-06)

[EN] Nonvolatile switching is still a missing functionality in current mainstream silicon photonics complementary metal-oxide-semiconductor platforms. Fundamentally, nonvolatile switching stands for the ability to switch ...
Ultra-compact non-volatile Mach-Zehnder switch enabled by a high-mobility transparent conducting oxide

Parra Gómez, Jorge; Olivares-Sánchez-Mellado, Irene; Ramos, Francisco; Sanchis Kilders, Pablo (The Optical Society, 2020-03-15)

[EN] Compact and broadband non-volatile silicon devices are mainly absorption based. Hence, access to low-loss non-volatile phase shifters is still a challenge. Here, this problem is addressed by using a high-mobility ...
