| 摘要 |
An optical bistable silicon Raman laser is disclosed, which provides digital signal regeneration, reshaping and wavelength conversion. An apparatus according to aspects of the present invention includes an optical waveguide disposed in semiconductor material. First and second reflectors are disposed in the optical waveguide. The first and second reflectors define a cavity in the optical waveguide. The cavity is to receive a first optical beam having a first wavelength. A power level of the first optical beam received by the cavity rising above a second power level results in emission of a second optical beam of a second wavelength from the cavity until the power level of the first optical beam received by the cavity falls below a first power level. The first power level is less than the second power level.
