[SungDae]

Hi, I'm Sungdae studying in Korea.

In common, making a energy state in the photonic energy gap.

but i don't know exactly what a different single-mode-cavity and 'single'-mode-cavity?

Thanks

There is normally no difference between the terms, the second may be a typo.

I see, but i heard single-mode-cavity is more used at fabrication. is there why this is popular ?

Thanks a lot.
