We propose and design a new kind of all-fiber polarization beam splitter and rotator (PBS
and PBR) based on vector-mode-assisted coupling. By embedding a high-contrast-index …

Optical couplers are very important devices in optical communication systems and optical
sensor systems. Several types of optical couplers with different materials or different …

In this paper, we propose an ultra-broadband polarization beam splitter for a dual hollow-
core anti-resonant fiber. We divide the fiber core into two parts by introducing the two longer …

To confront the growing challenges of integrated photonics, optical devices need to be
compact in size to integrate them in communication networks where a polarization beam …

We proposed a novel polarization splitter based on single-polarized elliptical-hole core
circular-hole holey fibers (EC-CHFs). We employed the full-vector finite element beam …

Here we propose an optical fiber interleaving filter based on a polarization-diversified loop
(PDL), which can offer a polarization-controlled free spectral range (FSR). The proposed …

In this paper, we design and demonstrate polymer-based polarization beam splitters
realized with parabolic graded-index (GI) directional couplers at 1550 nm. We design and …

We propose a compact highly-efficient CMOS-compatible polarization splitter and rotator
(PSR) with a wide bandwidth covering the whole O-band. It benefits from the different …

An ultracompact and broadband polarization beam splitter (PBS) based on the polarization-
dependent critical guiding condition of an asymmetrical directional coupler is proposed. The …

Optical-fiber-based polarization scramblers can reduce the impact of polarization sensitive
performance of various optical fiber systems. Here, we propose a simple and efficient …
