Silicon does not emit light efficiently, therefore the integration of other light‐emitting
materials is highly demanded for silicon photonic integrated circuits. A number of integration …

A concept for the bandwidth enhancement of directly modulated vertical-cavity surface
emitting lasers (VCSELs) using a transverse-coupled-cavity (TCC) scheme is proposed …

We explore the concept of passive-feedback lasers (PFLs) for direct signal modulation at 40
Gb/s. Based on numerical simulation and bifurcation analysis, we explain the main …

Increasing demand for higher data rates in data centers and high-performance computing
systems require optical interconnects that support more than 100 Gbps-per-lane …

A vertical cavity surface emitting laser (VCSEL) was born in Japan. The 37 years' research
and developments opened up various applications including datacom, sensors, optical …

We propose and demonstrate free-space optical (FSO) communication using photonic
crystal surface-emitting lasers (PCSELs). Unlike other types of conventional semiconductor …

This paper presents experimental and modeling results for extending the 3-dB modulation
bandwidth of a 980-nm quasi-single-mode (QSM) vertical-cavity surface-emitting laser …

In this paper a novel method to increase the modulation bandwidth of vertical-cavity surface-
emitting lasers (VCSEL) is proposed. The modeling predicts that the modulation bandwidth …

It is very attractive to apply a directly modulated laser (DML)-based intensity-modulation and
direct-detection (IM/DD) system in future data centers and 5G fronthaul networks due to the …

We produce experimental 980 nm vertical cavity surface emitting lasers (VCSELs) with a
wide range of oxide aperture diameters (ø) from∼ 2.5 to 15 µm on wafers designed to …
