We attended a seminar held by Minoshima-sensei at University of Electro-Communications. The content is about optical frequency comb and comb-based spectroscopy techniques.
We learnt a lot from Prof. Zhigang Zhang (Peking University), Prof. Youjian Song (Tianjin University), Prof. R. Jason Jones (University of Arizona), and Dr. Ruoao Yang (Peking University).

Participant: Maolin Dai, Bowen Liu and Yifan Ma.

Welcome all of you to become a part of our big family!

Dr. Shirahata-san has completed his research project successfully, and Horiuchi-san has completed her Master’s course. Congratulations to them! They will go for new positions, we wish them the best of luck for their future journey.

Alumni got together today, we had a great hanami along Meguro river !

Lab members enjoyed a weekend ski trip in Nagano-ken

Our lab was pleased to host a visit from 2010 Nobel Laureate Professor Sir Konstantin Novoselov. Prof. Novoselov was awarded the 2010 Nobel Prize in Physics for his pioneering work on graphene, a key component in our lab’s research. We were very proud to share our work with him.

The members of Yamashita-Set Lab visited the offices of Mitsubishi Electric Corporation on the 24th of October. Thank you for hosting us!

Lab members attended and presented their work at the 84th Autumn meeting of the Japan Society of Applied Physics in Komamoto on September 19 – 23.

Congratulations to doctoral student Bowen Liu, whose excellent work has been recognised at Optoelectronics Global Conference 2023.

Bowen’s paper “Bidirectional Polarization-Multiplexing Fiber Laser Enabling Tunable-Repetition-Rate Dual Combs” won the Best Student Paper Award and was highlighted on the cover of the conference proceedings.
