Types of Presentation

The time slot for each talk in oral sessions is listed below:

• Invited talk: 30 minutes

The last 5 minutes in each talk are set for questions and discussions.

• Contributed talk: 15 minutes

The last 3 minutes in each talk are set for questions and discussions.

• Poster sessions are scheduled for selected papers that may be better presented in details with more visual images, allowing poster presenters to share their viewpoints with visitors and have discussions one-on-one. Attendees can also study or restudy the information during the poster sessions.
• For poster sessions, OPTIC 2025 provides each presenter with a bulletin board on which the presenter can mount a poster [84.1 cm (W) × 118.9 cm (H)], and the presenters can provide flyers of the research if needed. Please note that presenters must be around their bulletin boards to make their presentations and answer questions during the poster sessions.

Notice:

• Submissions received after September 7, 2025, will, if accepted, be classified as poster presentations and will not be considered for the Best Student Paper Award.
