Nanophotonicsに先日、初めて論文を投稿した。Optica系と違って、レビュアーの何人とか、締め切りいつくらいとかは特に見れなさそう。IEEE系もただ単にUnder Reviewだったと思う。Optica系みたいな方がいいな。

I will give a talk at a symposium on optical computing, organized by a funding agency in conjunction with OECC/PSC 2025. It will be my first time attending OECC/PSC. photoniccomputing.jp/activities/202…

今日は空が綺麗だな(暑いけど…)

今年のコナンの映画に非線形光学が出てくるらしい。今年度、担当している非線形光学のレポートの感想で知った笑。 gakushikan.online/column/246

There are good papers everywhere e.g. Nature Photonics IF = 32.9 is based on 238 papers. Optics Letters (OL) IF = 3.3 is based on 3240 papers. Recomputing the IF of OL based on its top 238 papers gives IF ~ 12. A mistake to focus only on the left column I think.

My first PhD student (Kenji Nishimoto (西本健司)/ ) is starting a new chapter. I'm really grateful for the six years we spent doing research together. Wishing him all the best for his new life in Germany!

anti resonant hollow core fiberなるものが存在して、ここ10年くらいでどんどん進展して、通常のシングルモードファイバーのロスを下回るレベルに到達してるらしい。 全然知らないトレンドだった…。 opg.optica.org/oe/fulltext.cf…

Not パフェ, but 海鮮丼。

We have a guest from Foton Institut in Renne University. Our institute is eager to establish collaborations with other photonic institutes.
