Your current workMy primary responsibility as the leader of the Measurement Team at Koala Tech revolves around overseeing the characterization of OSLD (Organic Semiconductor Laser Diode) devices provided by our fabrication team. Our focus extends beyond this to examine the in-depth study of photophysical properties within optical gain materials synthesized by our dedicated Material Synthesis Team. Our work is important in understanding and optimizing the performance of the devices. We employ advanced optical and electrical measurement techniques specifically developed to characterize OSLD devices. These techniques, developed through our team's diligent efforts, allow us to investigate the devices in detail, ensuring comprehensive analysis and improvement. Beyond measurements, we utilize cutting-edge optical and electrical simulations to precisely design the device structure, predicting and estimating its performance even before fabrication begins. This proactive approach helps us fine-tune and optimize the devices for enhanced functionality and stability. Collaboration lies at the heart of our success. The collaboration among our teams not only facilitates the improvement of existing devices but also drives innovation by exploring novel methods to advance the practical applications of our organic semiconductor laser technology.

Successful experiences and things that made you happy at workWhen I joined Koala Tech, our R&D team focused on developing an innovative OSLD device capable of emitting highly directional and single-colored light. I actively joined with experts skilled in design and fabrication to contribute to creating this groundbreaking device. Eventually, we succeeded! Our team engineered a new device, a significant leap forward in the OSLD market. I had the opportunity to design and present a live demonstration of our new device at the prestigious International Display Workshop (IDW) in Niigata. The moment industry experts recognized and praised our team's achievement was truly remarkable. They even acknowledged it as the world's first of its kind! Witnessing our collective effort receive such acknowledgment and acclaim filled me with immense joy and pride.

company atmosphere and environmentWhen I joined the company, I immediately felt that it was a very welcoming environment, and if there was something I didn't understand about the company, the team members would quickly respond to me. Also, my supervisor usually seems busy, but when I talk to him, he immediately gives me accurate advice. During team meetings, I receive professional advice and always ask if I have any questions. Additionally, some of our equipment is shared with Kyushu University, so we are able to use expensive equipment, which is a great privilege. Everyone has a variety of nationalities and specialties, so it's refreshing to be able to absorb sensibilities and ideas that are different from my own. I think it's a good workplace where you can work at your own discretion, rather than being passive.

What kind of future do your research expect to lead?If the materials and technology that I develop can emit lasers at a lower cost than inorganic materials, and if the emission color can be tuned without increasing the number of synthesis steps, it can be applied to all kinds of devices, and it will be a strong technology and company. I think it will be.

Future goals and career planAs a researcher, I want to become an engineer who can propose molecular designs that achieve the physical properties of a target.

successful experiences and things that made you happy at workWhen I can isolate a target compound that could not be isolated before, or when a reaction that did not progress progresses, the effort is worth it. Also, if I can obtain the optical properties of a compound and use it as a hint for the next molecular design, your motivation will increase.
