Angle-Spliced SMF to Hollow Core Fiber Connection with Optimized Back-Reflect…

We study and demonstrate angle-cleaved fusion splicing between single mode fiber (SMF) and nested anti-resonant node-less fiber (NANF). First, we analyze the trade-off between the connection loss a…

The Generation of 1.2 μJ Pulses From a Mamyshev Oscillator Based on a High C…

We demonstrate a high-energy and high-average power Mamyshev oscillator based on a high performance large-mode-area step-index germanosilicate-cladding Yb-doped fiber. The oscillation of higher-ord…

Temperature Insensitive Delay-Line Fiber Interferometer Operating at Room Tem…

Environmental temperature fluctuations cause phase changes of the light propagating through optical fibers due to their thermal sensitivity. This limits the stability of fiber delay-line interferom…

Internal Gas Composition and Pressure in As-drawn Hollow Core Optical Fibers

We present a study into the gas pressure and composition within a hollow core optical fiber immediately after fabrication. Results from three different experimental techniques indicate that the ini…

Hollow-Core NANF for High-Speed Short-Reach Transmission in the S+C+L-Bands

Hollow-core fibers offer a range of beneficial properties for high-speed optical communication applications, including low latency, low chromatic dispersion and nonlinearity. Based on a system empl…

Optical Fiber Delay Lines in Microwave Photonics : Sensitivity to Temperature…

One of the key functionalities in microwave photonics is to be able to define controllable time delays during the signal processing. Optical fibers are often used to achieve this functionality, esp…

4-Level Alternate-Mark-Inversion for Reach Extension in the O-Band Spectral R…

Alternate-mark-inversion (AMI) has been used in the past to improve the transmission performance of binary intensity modulation formats. In this work, we improved the tolerance of O-band 4-level pu…

Polarization Effects on Thermally Stable Latency in Hollow-Core Photonic Band…

Conveyance of light in air endows hollow-core optical fibers with remarkably low sensitivity of the propagation delay to temperature changes. This sensitivity was demonstrated to be further reduced…

Ultra-Broadband Bismuth-Doped Fiber Amplifier Covering a 115-nm Bandwidth in …

In this article, we experimentally demonstrate an all-fiber optical amplifier using Bi-doped phosphosilicate fiber (BPSF) operating in both the O-band and the E-band, providing >20 dB gain from 134…
