| Abstract: | A DVD pickup based on dual wavelength integrated laser diode is developed. The dual wavelength laser diode can emit two kinds of light with different. Wavelength the 650?nm is used for DVD and the 780?nm is used for CD and CD R/RW. Some key problems about designing this DEV pickup are discussed. The feasibility of this scheme is proved by experimental results. |
