III-V-on-silicon nitride narrow-linewidth tunable laser based on micro-transfer printing

Publikováno v: 2023 Optical Fiber Communications Conference and Exhibition (OFC).

We demonstrate a narrow-linewidth tunable laser through micro-transfer printing a pre-fabricated III-V gain section on imec’s 200-mm Si/SiN platform. Lasing in distinct bands in the C+L band is demonstrated, with linewidth down to 2.87-kHz.

Wafer-scale 2.5D optics in the visible and near infrared for advanced light management

Publikováno v: Optical Architectures for Displays and Sensing in Augmented, Virtual, and Mixed Reality (AR, VR, MR) II.

The coming of age of AR, VR and MR applications and usage scenarios relies on the development of ever-improved advanced light management systems, both for sensing (camera) and actuation (display), e.g., solid-state dToF or FMCW scanning or flash LiDA

Impact of Post-deposition Plasma Treatment on Surface Passivation Quality of Silicon Nitride Films

Autor: Mehul C. Raval, Anil Kottantharayil, Sandeep S. Saseendran

Publikováno v: IEEE Journal of Photovoltaics. 6:74-78

Exposing a plasma-enhanced chemical vapor deposition-deposited silicon nitride (SiN $_{x}$ ) film to an inert gas-oxidizing plasma ambient results in a significant reduction in background plating in the case of electroplated Ni–Cu metallization on

Study of Nickel Silicide Formation and Associated Fill-Factor Loss Analysis for Silicon Solar Cells With Plated Ni-Cu Based Metallization

Autor: Mehul C. Raval, Sandeep S. Saseendran, Stephan Suckow, Anil Kottantharayil, Chetan Singh Solanki, Sekaran Saravanan, Amruta P. Joshi

Publikováno v: IEEE Journal of Photovoltaics. 5:1554-1562

In this study, the impact of impurities incorporated into plated nickel seed layer on silicide formation and the influence of annealing temperature on the fill-factor (FF) loss of solar cells with Ni-Cu contacts is investigated. The silicide growth o

Inverted Pyramidal Texturing of Silicon Through Blisters in Silicon Nitride

Autor: Anil Kottantharayil, Sandeep S. Saseendran

Publikováno v: IEEE Journal of Photovoltaics. 5:819-825

We have demonstrated a novel process for the fabrication of inverted pyramidal structures on silicon. The proposed technique uses no photolithography step and is instead replaced by a thin-film deposition step and thermal annealing. In this paper, in
