Benefits of technology

This patented technical effect described in this patents relates to improving the performance and efficiency of opto-electronic devices used for transmitting data over fiber networks (optics). By combining both light sources like vertically polarized LED's and horizontal polarizers together, it becomes possible to achieve higher signal transmission rates without increasing their size. Additionally, there has been developed a new method called quantum dots, where certain atoms have specific properties such as spin states at particular angles. These techniques help increase the amount of energy they use during operation while also allowing more precise control over how much power each atom releases when excited. Overall, these improvements make better ways to send signals through fibers than just sending them separately.

Problems solved by technology

Abstract

The invention belongs to the field of integrated optoelectronics and optical communication, and relates to an integrated orbital angular momentum mode transmitter. The integrated orbital angular momentum mode transmitter is constructed by integrally growing a substrate, a reflecting mirror structure, an active region, a transverse optical field and electric field limiting layer and a phase plate generating angular spiral phase distribution, thereby forming an independent integrated device. The phase plate generating angular spiral phase distribution can be a structured phase plate having a spiral continuous phase plate structure, a spiral stepped phase plate structure, a fork-shaped diffraction grating phase plate structure and a super-surface phase plate structure capable of providing spiral phase distribution along the angular direction. By adopting the integrated orbital angular momentum mode transmitter, high integration and miniaturization are realized, the device process is mature, and the structure is simple and is easy to realize. The wavelength of the angular momentum mode of a transmission orbit can be flexibly changed through selection of the structural parameters of a reflecting mirror as well as the material system and structure of an active layer. The integrated orbital angular momentum mode transmitter plays an important role in promoting the development of rapid orbital angular momentum optical communication.
