Submission Rules

  1. Posts must be relevant to lasercom.
    We like questions, news, discussion articles, published research, course content, educational resources or videos about Earth or space-based laser communication.

Comment Rules

The rules are pretty damn simple:

  1. Be respectful to other users.
    All users are expected to behave with courtesy. Demeaning language, sarcasm, rudeness or hostility towards another user will get your comment removed. Repeat violations will lead to a ban.

  2. No misinformation.
    If there is a question, don't just 'make stuff up' unless of course it's obviously a joke. This rule is simply to avoid assertions of pseudo-science or incoherent / uninformed rambling and keep the sub reliable and informative. Sometimes cutting-edge technology is pretty crazy and hard to believe. So when making wild assertions, we encourage you to post links to supporting references, or use valid reasoning.

    SDA compliant for Beaconless modulation

    Does someone know why the SDA standard requires amplitud modulation with a modulation index > 80% We are working on this for our EDFA but we found this requirement quite complex, specially the repetition rate required which is 50 & 60 kHz I try to look for more information about it but it doesn’t really says why they choose that. Any comments are appreciated

    Free Space Optical communication

    Could you suggest a research topic on the FSO? I can't decide which aspect of FSO I should focus my research on to do a PhD.
