Latest update: May 18th 2019

Welcome to the website of the World Technology Mapping Forum

HHI Headquaters in Berlin, Germany. This is the venue for WTMF-3

Registration for WTMF-3 is OPEN.

June 12 -14th 2019, in Berlin, Germany.

The third WTMF will be hosted by Fraunhofer Institute for Telecommunications, Heinrich Hertz Institute, Einsteinufer 37, 10587 Berlin Germany

PhotonDelta and the AIM Photonics Academy would like to invite you to participate in the third meeting of the World Technology Mapping Forum. This year’s summer meeting will be held at the Fraunhofer Heinrich Hertz Institute in Berlin, Germany from Wednesday June 12 – Friday June 14, 2019.

The goal is to update and discuss the Integrated Photonic Systems Roadmap – International (IPSR-I), looking ahead to global technology needs in 2030 and beyond. Following successful Fall and Winter meetings in Cambridge USA and Tokyo Japan, the latest draft of this new IPRS roadmap was issued to Working Group Leaders at the Spring meeting in Sunnyvale California in March.

Final Call - Registration Is Still Open.

Registration for the WTMF-3 is by invitation only because this is a highly technical working forum and not a general conference about photonics.. We have sent out invitations to last year's participants and those people who have already expressed interest in attending. If you feel can contribute to our technical working groups, we encourage you to send an email to Ms Lotte Krah immediately at this email address: Please give us details of your name, company/research organisation and your area of expertise that would be useful for the Integrated Photonic Systems Roadmap. You will then receive an invitation from us which explains how to register.  

Upon payment of the conference registration fee (which goes towards covering the costs of the meeting) we will send you any announcements and documentation you need to prepare. Please note that travel and accommodation costs are at your own expense.

Different Format for this year’s Forum - Agenda Published.

We are using this forum website to post exact details of the plenary programme as it develops. The first draft of the programme can be found here.

From your suggestions we are making changes to the format. Wednesday and Thursday morning will be devoted to industry keynotes and an interactive plenary discussion. Wednesday and Thursday afternoon is being reserved for the technical workshops (behind closed doors). Friday morning will contain the results of the workshops and discussion of what happens next with IPSR-International. Please note that this is a highly technical forum, not a general conference about photonics.

Recommended Hotel Accommodation - Now Open

June is a busy month for visitors to Berlin, so we suggest you book accommodation as soon as possible. We have opened a special page on this websitewith all the details you need to know about the recommended hotels. We have managed to secure special rates for forum delegates at five hotels within a short walking distance of the venue.

Travel Tips on Getting to HHI, in Berlin, Germany

By Plane

Berlin has two airports and excellent public transport. Consider buying a Berlin Welcome Card at the airport or on-line. This gives you unlimited travel on trains, underground and buses within Berlin for the duration of your stay.

Arriving at Tegel Airport (TXL)

By Taxi: 15 minutes.

By Bus 109 to station "S+U Zoologischer Garten", then change to bus 245 (with the heading "S Nordbahnhof") . Get off at "Marchbrücke". The main building at Einsteinufer and branch office at Salzufer are (1-3 minutes).

By bus X9 to bus stop "Ernst-Reuter-Platz", then either walking from Ernst-Reuter-Platz alongside Marchstraße to Einsteinufer (about 5 minutes) or going by bus 245 (headed to: "S Nordbahnhof") to bus stop "Marchbrücke".

Arriving at Schönefeld Airport (SXF)

By taking the (regional) express trains "RE7" or "RB14", operated by Deutsche Bahn (DB), you quickly arrive at the station "Berlin Zoologischer Garten". Then take bus 245 (headed to: "S Nordbahnhof") to bus stop "Marchbrücke". The sites at Einsteinufer and Salzufer can be reached on foot (1-3 minutes).

By suburban railway (S-Bahn line S9) to station "Tiergarten", and then walk alongside "Straße des 17. Juni" in direction "Ernst-Reuter-Platz" (westward) about 400 m. After crossing the channel bridge turn right into "Einsteinufer". Walking time is appr. 12 minutes.

Arriving By Train

"Hauptbahnhof" is Berlin's main station on the route of most of international, regional and inner-city trains. From here, take bus 245 (headed to: "Zoologischer Garten") to bus stop "Marchbrücke", which takes about 15 minutes. The main building of the Institute is close to the bus stop (approx..50 m).

Recap on WTMF-2018 using our special on-line magazine.

Last year's WTMF-2018 in Enschede was a great success, thanks to over 160 participants who attended. Discussions are continuing in regional meetings as the important work on the roadmap continues.

The 2018 WTMF online magazine includes complete videos of Wednesday Plenary Presentations and Debate, as well as the Friday morning Feedback presentations and wrap up from Lionel Kimerling and Ton Backx. The latest release was last updated on Friday June 29th 2018. We have added the indexed Powerpoints of the final presentations.

Why are we doing this? We are experimenting with new ways to capture and share the knowledge from the forum. We think this approach can serve as a blueprint to other deep-dive conferences. Conversations often stop because those who couldn’t attend can only access a Powerpoint. We believe this is rather like sending a colleague a feature film without the soundtrack. Not much use. This year, video recordings were made of the Wednesday and Friday presentations using a new near-real-time publishing technology we’re developing in the Netherlands. This is a dynamic document.
