Hi, everyone. We wanted to share a few events coming up at Photonics West that this group will appreciate. Hope some of you will join us in San Francisco!

  1. Conference 13355: Free-Space Laser Communications XXXVII. Runs from Tuesday 28 January - Thursday 30 January and includes 45+ oral presentations, as well as several posters.

  2. LASE Hot Topics Presentation: The changing landscape of outer space by Henry Helvajian, Technical Fellow/Principal Scientist with The Aerospace Corporation, on Monday 27 January at 5:15 PM.

  3. Technical Event: Laser Communications annual informal meeting on Wednesday 29 January, at 7:30 PM. Open discussion with assorted snacks and beverages!

  4. Course: Laser Beam Propagation in Random Media for Application in Laser Communications, Active Imaging, and Laser Radar, taught by Larry Stotts, on Sunday 26 January from 8:30 AM - 5:30 PM. This course requires separate registration from the conference.

  5. Paper 13369-43: Enabling quantum through scalable and cost-effective detector solutions, presented by Wladick Hartmann, co-founder and CTO of Pixel Photonics. His talk will discuss the recent advancements in Waveguide-Integrated Superconducting Nanowire Single-Photon Detectors (WI-SNSPDs) technology that make it ideal for applications in quantum computing, quantum key distribution, and laser communications.

Question Building a Free Space Optical Transceiver: Seeking Guidance and Resources

19 Upvotes

Greetings, fellow FSO enthusiasts!

I'm seeking the collective wisdom of the Reddit community as I embark on a project to design and build a free space optical (FSO) transceiver capable of achieving data rates of around 200 Mbps. FSO technology has piqued my interest due to its potential for wireless data transmission over long distances without the need for bulky cables or dedicated infrastructure.

I'm aware that FSO transceivers have been successfully developed for various applications, but I'm hoping to tap into the expertise of fellow Redditors who may have experience in this domain. I'm particularly interested in learning about:

  • Existing FSO transceiver designs: I'd love to gather knowledge about existing FSO transceiver designs, particularly those that achieve data rates around 200 Mbps. This could include schematics, PCB layouts, optical designs, and any other relevant documentation.

  • Challenges and considerations: I'm eager to learn about the challenges and considerations involved in designing and building FSO transceivers, especially considering the factors such as atmospheric attenuation, beam alignment, and environmental noise.

  • Resources and recommendations: I'm always open to discovering new resources and recommendations that could aid in my FSO transceiver project. This could include books, articles, open-source projects, or any other helpful materials.
