LOW-COST FAST VARIABLE OPTICAL ATTENUATOR FOR OPTICAL WAVELENGTH TRACKING |
摘要 |
Variable optical attenuator (VOA) formed by disposing upon a substrate a waveguide, a p-type region and an n-type region about the waveguide, and an epi-silicon region disposed upon the waveguide, the VOA responsive to a bias current to controllably inject carriers into the waveguide to attenuate thereby optical signal propagating through the waveguide.
