Microwave photonics (MWP) is an emerging field in which radio frequency (RF) signals are
generated, distributed, processed and analyzed using the strength of photonic techniques. It …

Of all oxides, lithium niobate (LiNbO_3) is the gold standard electro-optical material in fiber-
optic transmission systems. Modulators based on diffused waveguides in bulk LiNbO_3 …

Terahertz waves, which lie in the frequency range of 0.1-10 THz, have long been
investigated in a few limited fields, such as astronomy, because of a lack of devices for their …

A highly efficient phase shifter based on the silicon-organic hybrid (SOH) platform is
theoretically investigated and experimentally tested. The device consists of a silicon slot …

Optical phase shifters are extensively used in integrated optics not only for telecom and
datacom applications but also for sensors and quantum computing. While various active …

The explosive growth of data centers, cloud computing and various smart devices is limited
by the current state of microelectronics, both in terms of speed and heat generation …

We present thermally tunable microring optical filters using pip-type microheaters. The use
of Vernier effect in the cascaded two microring resonators significantly enlarges the free …

We demonstrate a fully-reconfigurable fourth-order optical lattice filter built by cascading
identical unit cells consisting of a Mach-Zehnder interferometer (MZI) and a ring resonator …

In this paper, we propose a new broadband nulling interferometer based on the Si 3 N 4/SiO
2 platform which utilizes a π-phase shifter. This π-phase shift multimode interference Mach …

We present a fully reconfigurable fourth-order RF photonic filter on SOI platform with a
tunable 3-dB bandwidth of 0.9–5 GHz, more than 38 dB optical out-of-band rejection, FSR …
