An innovative DVD pickup based on integrated dual-wavelength laser diode is developed. The dual-wavelength laser diode emits two lasers with di erent wavelengths. The laser with 650 nm wavelength is used for DVD, and the other with 780 nm wavelength is used for CD and CD-R=RW. Key techniques of this

## Abstract A new type of dumbbellβshaped defected ground structure (DGS) is introduced in this article. Its dualβbandgap characteristics are reported for the first time and can be adjusted by changing the dimension of complementary splitβring resonators (CSRR) unit and gap. The dual bandstop filte
