Usually, and especially for the IEEE conferences, it is easy to know whether a conference is good or not. For example, top-tier, second-tier and third-tier conferences are known and agreed upon.
For example, the IEEE ICC (1st tier) conference is better than IEEE Globecom (2nd tier). My question is, how to define the tiers for the OSA meetings and conferences.
Is there anyone familiar with the OSA meetings and conferences who can shed the light on how to interpret the acceptance in an OSA conference? What tier does an OSA conference belong to? How to know it, etc....
Kindly note that I am not asking if the acceptance as a poster, or even a talk is prestigious. I am strictly interested in the classification of the meeting and conference.
I know that a poster acceptance is less than being accepted for a talk, and that it is merely for discussions and feedback on new or emerging research topics. However, I believe that a poster presentation in a top tier, is better than a poster presentation in a second tier, therefore, I am asking about the OSA meetings and conference classifications.
