The project focuses on inter-city collaboration in the development of photonics technology. Our goal is to establish a network and operational model between different cities that can effectively be utilized to promote innovation in photonics. The project is built on strong cooperation and knowledge-sharing among cities, which is an essential part of supporting the growth and success of the photonics industry. The project also supports the development of Chip Act functions in partner cities, including Joensuu, Tampere, Oulu, and the Greater Helsinki area. Inter-city collaboration generates synergies, strengthens research environments, and enables more efficient use of resources. The core of the project lies in five key work packages: Work Package 1: Building a National Inter-City Cooperation Network The aim is to strengthen the national cooperation network among different cities. This network brings together businesses, research institutions, and experts from different regions, creating synergies and advancing the development of the photonics industry. Business Joensuu is responsible for this work package. Work Package 2: Increasing and Strengthening International Photonics Networks Our project expands and strengthens inter-city collaboration on an international scale. This work package focuses on establishing strong connections with international stakeholders and facilitating global cooperation. BusinessTampere is in charge of implementing this work package. Work Package 3: Developing a Communication Plan and Key Messages for Promoting Photonics The project's benefits and achievements need to be effectively communicated. This work package centers on crafting a communication plan that clearly and persuasively conveys the significance of photonics and the benefits of collaboration. Business Joensuu is responsible for this work package. Work Package 4: Preparation of Investment Processes Inter-city collaboration provides a solid foundation for attracting investments to Finland. Our goal is to offer an attractive environment for the development of photonics, which will draw both domestic and international investments. Business Joensuu is responsible for this work package. Work Package 5: Ensuring Flexible Access to Existing Research Infrastructure for Photonics Companies Inter-city collaboration improves photonics companies' access to existing research infrastructure. This support promotes innovation and development within companies while simultaneously strengthening the competitiveness of the entire industry. VTT is responsible for implementing this work package. At the core of our project is inter-city collaboration, which establishes a strong foundation for the success of the photonics industry. Through collaboration, we can achieve more and create better conditions for the growth, research, and innovation of the industry. The project's results include: National Inter-City Cooperation Network: • The network has been established, and cities' expertise profiles and offered opportunities have been defined. • Research and development infrastructures have been identified and are now in use. • The network's activities have commenced, and stakeholders have actively participated. International Photonics Networks: • International networks have been strengthened, and the sense of community between partner cities has increased. • Companies have actively participated in joint workshops and events. • Common goals and objectives have been defined within the collaborative networks. Communication Plan and Key Messages for Promoting Photonics: • A communication plan has been developed, and key messages about the potential of photonics have been planned and created. • Active communication has been conducted for target companies and internationally. Preparation of Investment Processes: • Participation in events and occasions has increased awareness among companies and investors about the Finnish photonics industry. • Potential target customers and companies within the collaborative network have been identified. • Potential investors and customers are invited to meetings and events in Finland. • Plans and information for investors are presented attractively. • Advancing investment acquisition in Finland is facilitated through the collaborative network. Enhanced Utilization of Research Infrastructure: • Photonics-related infrastructures in partner cities have been compiled and presented. • Marketing materials have been produced for promoting expertise in photonics. • Investments by companies in Finland have been promoted through the services of regional growth and internationalization. As a result of the project, a model for the operation of the city network will be created, the expertise profiles of cities will be clarified and turned into a comprehensive communication, and added value will be brought to the participation of cities in Chip Act activities.
