Waveguide coupled III-V photodiodes monolithically integrated on Si
Pengyan Wen, Preksha Tiwari, Svenja Mauthe +8
The seamless integration of III-V nanostructures on silicon is a long-standing goal and an important step towards integrated optical links. In the present work, we demonstrate scal…
Hybrid III-V Silicon Photonic Crystal Cavity Emitting at Telecom Wavelengths
Svenja Mauthe, Preksha Tiwari, Markus Scherrer +5
Photonic crystal (PhC) cavities are promising candidates for Si photonics integrated circuits due to their ultrahigh quality (Q)-factors and small mode volumes. Here, we demonstrat…
Scaling of Metal-Clad InP Nanodisk Lasers: Optical Performance and Thermal Effects
Preksha Tiwari, Pengyan Wen, Daniele Caimi +4
A key component for optical on-chip communication is an efficient light source. However, to enable low energy per bit communication and local integration with Si CMOS, devices need…
Wurtzite InP Microdisks: from Epitaxy to Room-Temperature Lasing
Philipp Staudinger, Svenja Mauthe, Noelia Vico Triviño +3
Metastable wurtzite crystal phases of semiconductors comprise enormous potential for high-performance electro-optical devices, owed to their extended tunable direct band gap range.…
