Single-Mode Emission in InP Microdisks on Si using Au Antenna
Preksha Tiwari, Anna Fischer, Markus Scherrer +3
An important building block for on-chip photonic applications is a scaled emitter. Whispering gallery mode cavities based on III-Vs on Si allow for small device footprints and lasi…
Coupled VO2 oscillators circuit as analog first layer filter in convolutional neural networks
Elisabetta Corti, Joaquin Antonio Cornejo Jimenez, Kham M. Niang +5
In this work we present an in-memory computing platform based on coupled VO2 oscillators fabricated in a crossbar configuration on silicon. Compared to existing platforms, the cros…
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.…
