Low frequency under-water acoustic signal detections are challenging, especially for marine
applications. A Mach-Zehnder interferometric hydrophone is demonstrated using …

We demonstrate a widely tunable dual-wavelength erbium-doped fiber laser that used a 10-
cm photonic crystal fiber as a Mach–Zehnder interferometer to filter out the switchable dual …

We propose and experimentally demonstrate an approach to generate and distribute secret
keys over optical fiber communication infrastructure. Mach-Zehnder interferometers (MZIs) …

In this paper a novel photonic crystal (PC) phase comparator is proposed. The proposed
structure can be used in a PC Mach–Zehnder as the signal adder section to improve its …

A high output power, stable wavelength spacing and switchable multi-wavelength erbium-

Photonic crystal fibers (PCFs), also known as microstructured optical fibers, are a
highlighted invention of optical fiber technology which have unveiled a new domain of …

In this paper, we develop an alternative all-fiber interferometer, which is based on a
commercial graded-index multimode fiber mismatch spliced between two single-mode …

We demonstrate a novel, compact and low-loss photonic crystal fiber modal Mach-Zehnder
interferometer with potential applications to sensing and WDM telecommunications. By …

We experimentally demonstrated a simple dual-core photonic-crystal-fiber-based MZ
interferometer by use of femtosecond laser drilling and fiber splicing. A higher order mode is …
