In free-space optical passive devices such as optical isolators, optical circulators, optical switches and so on, the end faces of the input and output optical fibers must be separated by a certain di...

The processing process of fiber array is that the exposed optical fiber part with the optical fiber coating removed is placed in the V-shaped groove, pressed by the pressed part and bonded by adhesive...

2D (two-dimensional) fiber array is a kind of microlens array using end faces in large multicast switches,and is a connecting device for realizing large-scale switching through multi-path collimated l...

Polarization maintaining coupler is the key device to realize coupling, splitting and multiplexing of linearly polarized light. Its characteristic is that it can stably transmit two orthogonal linearl...

1. What is a polarization maintaining fiber coupler?Polarization maintaining fiber coupler is a device for detachable (movable) connection between optical fiber and optical fiber. It precisely connect...

Ⅰ. The key parameters of the fiber array are as follows1. The number and type of fibers (base material);2. Their spacing and (for 2D) the type of lattice used;3. The core diameter and numerical apert...

Fiber arrays have quite a variety of applications. Some typical cases are given in the following section.1. The fiber array is coupled to the photonic integrated circuitPhotonic integrated circuits an...

1. What is an fiber array?The fiber array (or fiber array unit) is a one-dimensional or two-dimensional fiber array. Usually, such an array is formed only for the end of a bundle of fibers, rather tha...

1. Use fiber array in astronomical telescopesFibers are sometimes used to transmit light from the telescope to other equipment for further analysis, such as high-resolution spectral analysis. Here, th...

1. The fiber end of the fiber arrayIt is often important to carefully fabricate the fiber array so that the fiber ends are well aligned in all dimensions. In addition, the input end or the output end ...

Fiber array (FA) has been widely used in optical communications and other fields. With the expansion of application fields, the demand for high-speed, high-density fiber transmission has become more a...

Polarization-maintaining fibers form fast and slow orthogonal axes due to the strong birefringence of the core, and light polarized along the fast axis has a smaller refractive index than light polari...

Polarization-maintaining fiber can maintain the polarization state of the beam propagation, and has a strong ability to resist environmental interference, so it is widely used in polarization-related ...

The polarization-maintaining fiber coupler is a key component to realize the coupling, splitting and multiplexing of linearly polarized light. Its characteristic is that it can stably transmit two ort...
