• Title: 100G and Beyond for PON and Short Reach Optical Networks• This tutorial focuses
on the key technologies for fixed-and mobile-oriented PONs. The former includes direct …

Directly modulated lasers (DMLs) have been implemented in short-reach optical networks
as an intensity modulation and direct detection (IM-DD) scheme due to their high output …

In this paper, we numerically and experimentally present the bandwidth constraints of a cost-
effective 5G mobile fronthaul based on a directly-modulated laser for data modulation and a …

Single-mode (SM) vertical-cavity surface-emitting lasers (VCSELs), especially those
operating around 850 nm, have been studied intensively in recent years for short distance …

Targeting high-speed, low-cost, short-reach intra-datacenter connections, we designed and
tested an integrated silicon photonic circuit as a transmitter engine. This engine can be …

Enhancing spectral efficiency (SE) of ultra-dense wavelength division multiplexing passive
optical network (UDWDM-PON) is vital to providing broadband access for massive users …

In this paper we present an experimental analysis of several modulation formats (pulse
amplitude modulation (PAM-2), quaternary pulse amplitude modulation (PAM-4) and …

Researchers have developed a uniform grating DFB with an integrated active optical
feedback waveguide (UG-AFDFB) to enhance the modulation speed of direct modulation …

Optical access networks are playing a more critical role in providing diverse emerging
applications for human-and machine-type communications. With the ever-growing demand …

The digital-analog radio-over-fiber (DA-RoF) scheme offers a high-fidelity and spectrally
efficient solution for future mobile fronthaul. However, to be implemented in the low-cost …
