We report novel high-bandwidth InP-based Mach–Zehnder modulator and in-
phase/quadrature (IQ) modulators that we realized by combining an nipn heterostructure …

This paper describes the problematic filter narrowing effect in the context of next-generation
elastic optical networks. First, three possible scenarios are introduced: the transition from an …

In order to meet the constantly rising traffic demands in optical transport systems for data and
telecommunications, compact, power efficient, and low-cost optical transmitters are needed …

We developed the world's first InP-based C+ L-band coherent driver modulator (CDM) that
has a 3-dB electro-optic (EO) bandwidth of over 90 GHz. The CDM consisted of an InP …

We developed a semiconductor regrowth scheme for InP photonic integrated circuits (PICs)
with optical-gain sections. Unlike conventional semiconductor regrowth schemes, a limited …

we report on an integrated InP based polarization rotator scheme using the plasmonic effect.
It operates as a half-wave retarder in ridge waveguide structure. The rotation angle of the …

The term DCI, an acronym for data center interconnect, is generally accepted to refer to the
optical interconnects between physical data centers that traverse distances greater than 2 …

We demonstrated semiconductor optical amplifiers capable of operating at 64Gbaud for 16-
64QAM modulation with large dynamic ranges. The full characterizations of SOA as …

We propose and demonstrate a silicon-photonics-based laser that outputs multiple
independently tunable wavelengths using a single InP gain element. We use it to generate a …
