| 英文摘要 | An optical filter is formed from at least two grating located in a waveguide region of a semiconductor optical device. Each grating has a multiple peak optical passband. The gratings are spaced apart in the waveguide region and form an optical cavity having a comb-filter characteristic. The gratings may be located in the active region of an optical gain element and in a preferred example are superstructure gratings (SSGs). A number of filters may be joined together in series. |
