Abstract:
1. A method for optical amplification using a silicon (Si) nanocrystal embedded silicon oxide (SiOx) waveguide, the method comprising: providing a Si nanocrystal embedded SiOx waveguide, where x is less than 2, formed by depositing a Si nanocrystal embedded SiOx strip using a high density plasma-enhanced chemical vapor deposition (HDPECVD) process; supplying an optical input signal to the Si nanocrystal embedded SiOx waveguide, having a first power at a first wavelength in a range of 700 to 950 nanometers (nm); pumping the Si nanocrystal embedded SiOx waveguide with an optical source having a second power at a second wavelength in a range of 250 to 550 nm; generating an optical output signal having a third power, greater than the first power, at the first wavelength, with a quantum efficiency of greater than 10%.
