Description

Vertical optical fiber clamp

Technical Field

Background

The coupling is an important production process of a planar optical waveguide device and a device, is a key part of the optical performance and the reliability performance of a product, and the process control of the coupling also becomes a key part of the quality of the device.

A multicore fiber can be simply defined as having multiple cores in a common cladding region, and since the single mode fiber channel capacity is increased to 100Tbit/s, which is close to the limit, the multicore fiber offers the possibility of increasing the fiber communication capacity. However, in the currently used communication devices, a single-mode fiber outputs a signal, and if multi-core fiber communication needs to be sufficiently fused to a communication system, low-loss connection between a multi-core fiber and the single-mode fiber is required, so that a multi-core fiber coupling technology is particularly important, and is a key factor for popularizing practical application of the multi-core fiber and reducing cost.

The existing chip waveguide coupling basically adopts optical fibers with single diameter, so that the limitation of optical fiber coupling is large, and the optical fibers with different diameters cannot be replaced, so that the chip is greatly restricted in the aspect of waveguide coupling research.
