N2 - As we have discussed, the year 1970 was an important year for the laser diode. That was the year Bell Laboratories achieved the continuous wave operation of laser diode in room temperature and Corning developed the low-loss optical fiber. By chance, the wavelength at which the low transmission loss was achieved, 800 nm band, matched the wavelength of the GaAs substrate laser diode that achieved the continuous wave operation in room temperature. As the previous chapter described, these innovations facilitated the advancement of laser diode R&D into the 1970s and focused R&D attention on optical communication.
