Electrical Engineering Photonic Devices

If you aren’t up to date with the recent news related to electrical engineering photonic devices, a small group of researchers from the University of California in San Diego have successfully built the smallest Nano laser to date. Along with that, they’ve also invented a startling new way of focusing the photons of a laser without any waste. But in case you don’t know a lot about electrical engineering photonic devices, let me first fill you in.

An Overview of Electrical Engineering Photonic Devices

Photons define the use of electrical engineering photonic devices to a great extent. They are what make up light particles and waves. There are many different processes it can be applied to. These processes include the generation, modulation, amplification, transmission, switching, signal processing, emission, detection and sensing of light. These are all represented in the whole light spectrum from ultraviolet all the way to the far-infrared. Some of the basic applications it can be applied to are light sources, transmission media, amplifiers, detection, modulation, and photonic systems.

Electrical Engineers Build New Optical Laser

The biggest breakthrough related to their new Nano laser is how it doesn’t require much power to operate. So due to how small these are, this group of electrical engineers have reported that this may well be a scientific breakthrough for future optical circuits on tiny micro-chips (used for computers). Due to the no waste end of it, it should be usable for determining new meta-materials for all researchers.

Meta-materials, or artificially structured material, studied from super-lenses can be used for seeing individual viruses, DNA molecules, and even cloaking devices that move light around an object that make it seem invisible. Also noted from this new finding was how all lasers require a pump action from an outside source to begin lasing. The smaller a laser is, the more pump action or power that is required for starting a coherent output for producing spontaneous emission.

So in response to this problem, this team of electrical engineers built a design using quantum electro-dynamic effects in coaxial Nano cavities to help stop the threshold constraint. This new invention has given leeway towards the development of even smaller nano-scale structures. This will allow further research into studying even tinier nanoscale laser light structures that are smaller than the wavelength of light itself. It is later hoped that these lasers can be pumped electrically instead of optically. This research will make it possible for people like you and me to have more efficient and advanced technology in the near future.
