To realize on-chip optical communication schemes based on silicon, the integration of waveguides onto III-V devices must be achieved. Here, the authors report waveguide-coupled III-V heterostructure photodiodes monolithically integrated on silicon wa

Direct epitaxial growth of III-V on Si for optical emitters and detectors remains a challenge. Here, the authors demonstrate in-plane monolithic integration of an InGaAs nanostructure p-i-n photodetector on Si capable of high-speed optical data recep

It is a long-standing goal to leverage silicon photonics through the combination of a low-cost advanced silicon platform with III-V-based active gain material. The monolithic integration of the III-V material is ultimately desirable for scalable inte

III-V semiconductors are ideal for light sources due to their tunable and direct band gap in the telecommunication band [1] , [2] , but their monolithic integration on Si is challenging, because of the significant thermal, polarity and lattice mismat

We demonstrate the first in-plane waveguide butt-coupled high-speed III-V p-i-n photodetector monolithically integrated on standard SOI and demonstrate data reception at 50 GBd using OOK and a 3 dB cut-off frequency approaching 70 GHz.

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 to be further scaled down. In this work, we fabricate micro- and nano

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 scaled and waveguide coupled III-V photodiodes monolithically integrated o

In this work we will discuss the use of Template-Assisted Selective Epitaxy (TASE) for the monolithic in-plane integration of active III-V photonic devices on silicon. We will show the use for highspeed InGaAs detectors, as well as for hybrid III-V/S

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 demonstrate a novel concept of a one-dimensional hybrid III-V/Si PhC cavity whic

We compare InP microdisk lasers on Si of varying dimensions with and without a gold cladding. We observe evidence of lasing in the NIR at room temperature upon optical excitation. Au-clad InP cavities lase at smaller dimensions beyond the limit achie
