regarding raman strain measurement http://www.dymek.com/en/products.asp?id=154&dlm=4 and energy band structure http://www.materialsdesign.com/appnote/energy-band-structure-germanium thanks

Hi! I'm sung dae with tensile strain, energy band structure could be changed. bang gap decrease with compressive strain, energy band structure could be changed. bang gap increase but I'm not sure why it could be changed .. Is there someone who explain in detail ? thanks. have a nice day! :)

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

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
