Mode-locked thulium-doped fiber laser with microfiber based polarization beam splitter

open access: yesResults in Physics, 2020
We report on a passively mode-locked thulium-doped all-fiber laser utilizing our fabricated microfiber-based polarization beam splitters (PBSs). The all-fiber PBSs composed of two parallel and coupled microfibers are fabricated to separate light in two ...

Optical Performance Monitoring for Intra-LP-Mode Dispersion in Weakly-Coupled Mode-Division Multiplexed Systems

open access: yesIEEE Photonics Journal, 2022
Weakly-coupled mode-division multiplexing (MDM) technique based on linearly-polarized (LP) modes in ultralow-modal-crosstalk few-mode fiber (FMF) has been considered as a promising candidate for capacity enhancement of next-generation optical ...

Сompensator of polarization mode dispersion based on spiral-wound single-mode fiber [PDF]

open access: yesТехнологія та конструювання в електронній апаратурі, 2013
A polarization mode dispersion (PMD) compensator for single-mode optical fibre has been designed. Its operation principle is based on the use of artificial difference of phase velocities of the basic ordinary and extraordinary waves in spiral-wound fibre,

INFLUENCE OF POLARIZATION MODE DISPERSION ON THE EFFECT OF CROSS-PHASE MODULATION IN INTENSITY MODULATION-DIRECT DETECTION WDM TRANSMISSION SYSTEM

open access: yesInternational Islamic University Malaysia Engineering Journal, 2010
Cross-phase modulation (XPM) changes the state-of-polarization (SOP) of the channels through nonlinear polarization rotation and induces nonlinear time dependent phase shift for polarization components that leads to amplitude modulation of the ...

The characterization of step index single mode silica fiber for long haul signal communication

open access: yesMaterials Research, 2005
The optical properties of single mode fibers, which are drawn from the silica preform made by MCVD technique, have been studied. The properties such as cutoff wavelength, chromatic dispersion, and polarization mode dispersion (PMD) were studied for 2.3 ...

Extreme outages caused by polarization mode dispersion [PDF]

open access: yesOptics Letters, 2003
We study the dependence on fiber birefringence of the bit-error rate (BER) caused by amplifier noise in a linear optical fiber telecommunication system. We show that the probability-distribution function of the BER obtained by averaging over many realizations of birefringent disorder has an extended tail that corresponds to anomalously large values of ...

Engineered extracellular vesicles enriched with the miR‐214/199a cluster enhance the efficacy of chemotherapy in ovarian cancer

open access: yesMolecular Oncology, EarlyView.
Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...

A novel quinazolinone insulin receptor inhibitor and its synergy with an EGFR inhibitor in glucose‐driven glioblastoma

open access: yesMolecular Oncology, EarlyView.
The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in
