What is a grating coupler?
Publish:Box Optronics  Time:2024-07-03  Views:95
The grating coupler uses grating technology to couple optical signals into optical fibers, and uses the principle of grating diffraction to connect the transmitted optical signals with the optical field inside the optical fiber. The fundamental principle is to use high-frequency acoustic wave fields as gratings to divide light waves into many small light waves, and project them into optical fibers, thereby realizing the coupling and transmission and reception of optical signals.
Main applications of grating couplers
1. Communications field
In traditional optical communications, grating couplers have been widely used in holographic storage and optical fiber communication systems. With the continuous development of communication technology, grating couplers have gradually been used in smart homes, machine vision and other fields
2. Optoelectronics field
The grating coupler can couple light beams to photoelectric sensors or optical devices to achieve photoelectric conversion. This application is widely used in wireless communications, wireless electronic products, intelligent sensing technology and other fields.
3. Life science field
In the field of life sciences, grating couplers are widely used in research fields such as cell imaging, cell diagnosis and treatment, pathogen detection, etc., and also provide new treatment technologies for the medical field, such as photodynamic therapy.
