Amorphous silicon nanowires combining high nonlinearity, FOM and optical stability

“…a more rapid increase in 1/T). Due to this limitation, the 1/T curve is fit at low powers up to ~1.2W with the following linear equation valid in the presence of both linear propagation loss and TPA [23]:…”

Nonlinear properties of and nonlinear processing in hydrogenated amorphous silicon waveguides

“…First, the time-averaged transmission of this picosecond pulse train (4ps, rep rate 10 MHz, center wavelength 1550 nm, spectral width 0.67 nm) in a sufficiently long (1.1 cm) photonic nanowire was measured as a function of the coupled input pulse peak power. It has been shown that the inverse of this transmission is linear as a function of the power [16] in the low power regime, when the free carrier absorption is negligible. The inverse of the transmission is given by [16] …”

All-optical high speed NOR gate based on two photon absorption in silicon wire waveguides

“…The amount of absorption is proportional to the square of the intensity [7] and the maximum transmitted power is limited. If there are two light beams with slightly different energies (or wavelengths), with one source at high peak power (pump) while the other one at low power (probe), the high power pump source will then induce absorption of the low power probe signal.…”
