The idea of an online conference has been percolating within the twittersphere for some time to address several well-acknowledged issues with the conventional conference format; namely, the large carbon footprint of conference travel, the impact of travel on work/life balance, and the increasing rates of disruption and cost of international travel. In parallel, the technical platforms designed for hosting a multi-location and open forum have significantly advanced, further motivating the development of alternative mechanisms for research dissemination. 

The initial mission of POM was to provide everyone access to the latest knowledge. Lately, especially due to the pandemic of COVID-19, it has become more important than ever to promote methods of disseminating scientific knowledge without physical contact.

Therefore, in addition to exchanging technical information to the photonics community, POM has a larger overarching mission. Briefly, the main goals are:

  • improve accessibility of conference attendance
  • reduce carbon footprint of conference travel
  • reduce burden on family of conference travel
  • reduce the cost of conference participation

Our inspiration comes from several places. The references below are just a small sampling of the many discussions currently occurring around the world trying to develop alternative approaches to scientific meetings. If you have articles that you would like to see posted, please send a link!


In September 2019, a committee of seven researchers decided to take a leadership role in implementing a virtual conference, creating the Photonics Online Meetup. The inaugural POM was held on January 13th 2020, and was entirely free for everyone.  Over 1000 researchers gathered simultaneously online for the first POM, attending the five-hour-long conference either alone from their personal computers or at their institution from hubs distributed across five continents and many time zones. 

The complete official POM20Ja program can be downloaded here [1 MB PDF].

This is the map of the hubs and participation in the first edition of POM.

We summarised what we learnt from this initial experience in the following publication:
