Online Poster Session

The Online Poster Session will start during the morning of January 12, 2021, and will continue throughout the day. Participants are encouraged to post at the time that is most convenient for them, depending on their timezone. All official virtual posters will be retweeted from @PhotonicsMeetup.

What is an online poster session?Twitter Poster session

Unlike a conventional poster which consists of a single sheet of paper that is several feet wide and tall, the online poster session will take place on Twitter, where participants will tweet their “posters”. A single tweet will include four images along with a brief summary, as shown in the example.

To maximize interaction during the POM Poster session, we strongly encourage you to set up a personal or laboratory Twitter account, if you do not have one already. This will ensure that you will be able to interact with other posters in the session as well.

If you do not have access to Twitter, please send your poster to We will send your poster out as a tweet from the official @PhotonicsMeetup account. You are encouraged to include your contact information (email address, etc.) on the poster slides, to facilitate further interaction with anyone interested in your work.

Preparing your images and tweet for posting

To ensure that your images are the correct aspect ratio, we have prepared a powerpoint template that is posted on the conference website. This series of four slides already has the correct aspect ratios and font sizes to accommodate twitter. These slides were used to create the tweet shown above. There are several aspects that must be considered when designing the images and when posting:

  • Aspect ratio and legibility of images on twitter
  • Number of images that can be contained in a single tweet
  • Hashtags for increasing visibility and associating poster with conference

A typical text for your tweet should contain the right hashtags (with # and your poster topic) and tag (@ your co-authors or affiliation additionally to @PhotonicsMeetup) :

We demonstrated this cool and impressive integration of photonics and biosensing. The implications for applications A and B are substantial. @PhotonicsMeetup #POM21ja #POM21bio    <poster in 4 images> 

The #POM21ja must always be included or the poster will not be retweeted. The other hashtags should be included if you submitted to one of the three main #POM21ja topics or if you want your poster to be associated with one of these topics: #POM21bio #POM21combs #POM21meta #POM20other.

To help you prepare your poster, we are providing a PowerPoint template and some additional guidance:
