Welcome to the home page for the Optical Terahertz Science and Technology conference series.

The OTST conference was founded to provide a venue for researchers using optical techniques to access the terahertz spectral range. This small workshop is held in March or April, every other year. It features both invited and contributed presentations from researchers worldwide, highlighting the latest results in generation, detection, spectroscopy, imaging, and applications of terahertz science.

NEWS: Information on the next OTST conference

        Location: Santa Fe, New Mexico USA

        Dates: March 10-15, 2019

        Chairs: Hou-Tong Chen and Igal Brener

More information will be forthcoming.

HISTORY:  OTST was founded in 2005, at a time when the terahertz community was beginning a period of rapid growth and activity. The vision for the conference is to remain relatively small (fewer than 200 participants), in the model of a Gordon Conference, to promote discussion and allow scientists at all stages of their careers to connect and collaborate. In 2005 and 2007, the conference was sponsored by the Optical Society of America, as an OSA Topical Meeting. Beginning in 2009, OTST became an independent conference series, with all of the responsibilities for the technical program and local organization handled by the two conference chairs. The 2013 workshop in Kyoto Japan was the first held outside of the USA; the 2017 meeting in London was the second. In 2019, the conference will return to the USA.

SELECTING THE NEXT OTST SITE: The current and former OTST Chairs have recognized the need for a more formal procedure for deciding on the location and the Chairs of subsequent meetings.  Starting with the 2021 conference, any person(s) interested in acting as Chair and host should prepare a brief document (pdf format) outlining their proposal. This document should contain, at a minimum, the following information:

·        Names of the two conference chairs and their affiliations; their history of previous attendance at OTST.

·        Proposed conference dates and location, including details of the location’s capacity for handling a meeting of this sort (i.e., a full week with one technical session at a time, not parallel sessions); any previous conferences of comparable size (200 attendees) hosted at that location; access to transportation, especially for international attendees; visa requirements (if any); estimated hotel costs for participants.

·        Budgetary information, including income from conference fee and expenditures associated with reserving the venue, refreshment/dinner, etc. Please be aware that OTST does not have any ongoing external support, either in the form of funding or staff/personnel, so these issues must be considered carefully.

·        Local amenities / proposed conference outing sites.

This brief proposal must be provided to the current OTST Chairs at least six months prior to the start of the preceding conference. (That is, proposals to host the 2021 meeting should be submitted at least six months prior to the 2019 meeting.) The steering committee, composed of all current and former OTST Chairs, will review all proposals prior to the conference, and will make a final selection by majority vote of attending members during the conference (absentee voting not permitted).
