Research output: Chapter in Book/Report/Conference proceedingChapter


The previous chapter looked at the competition for shorter wavelengths in laser diodes for the recording of optical information. The wavelength was shortened from 780 nm for CDs to the 600-nm band. In this chapter, we will look at the competition for even shorter wavelengths from the 600-nm band (red) to the 400-nm band (blue).
